When I watching this video this looks so easy but when I taking the test it's really hard! How would, for example 2z-7-1 = 2z + 8(4 votes). Then I can combine the like terms, shown with parenthesis: (2x - x) + (3y - 2y) + (4z - 3z). If I have 5 x's and I were to take away 2 x's, is how many x's am I going to be left with? In this case, that thing are x's. Which expression is equivalent to 4y 2. When there is an equation like this -4q - (-8q) +10, where there is a minus sign in front of the brackets, the sign(s) inside the brackets get changed.
Then i have plus 8z, and then I have minus z. You can't combine any further as p can be anything and there are four of them. Cancel the common terms. Why is X the most common letter used in math? They're the number that you're multiplying the variable by. So I have 5x-- that's that term-- minus 2x.
Like for example 4p +6 −3 how would you solve that? I am confused where did the (4-1) come from? Check the full answer on App Gauthmath. Okay now I've watched this and I'm still a little confused(4 votes). Equivalent Expressions. Where there is the 3y - 2y I can replace that with y: x + y + (4z - 3z). The mathematical property which allows us to do so is the commutative property of addition, which says, essentially, that, "when adding things up, order doesn't matter, " so x+y+z=x+z+y=z+y+x etc. We added the coefficients-- 7 plus 3-- to get 10y. This happens around2:50to3:00(6 votes). Example 4: Consider the first expression for any non-zero values of the variable. But if the values are plugged in the expression, both the expressions give the same result. Now let's think about the y's. And then you could see, oh, yeah, you definitely did add the two coefficients, the 8 and the negative 1. Which expression is equivalent to 3b 2r 4b r.o. I thought the answer is - 12q + 10. bcoz the the rule is "negative minus negative" the number will be just get more negative?
So, there is at least one pair of values of the variables for which the two expressions are not the same. And then the last term that I haven't included yet is that plus 5. Do you feel like you are improving or just getting by? Subtracting a z is the exact same thing as subtracting 1z. Which expression is equivalent to 3b 2r 4b r e. I cannot answer your question. Solution: Given expression: 3x+9. The first expression is the sum of 's and 's whereas the second one is the sum of 's and 's.
Good Question ( 61). So we can take 5 x's and take away 2 x's. But I don't know if... (7 votes). That's true of anything. Now, in a lot of algebra classes, you'll hear people say, oh, well, you know, the coefficient on 5x is 5. Generally, if two things are the same, then it is called equivalent. Similarly, in mathematics, the equivalent expressions are the expressions that are the same, even though the expression looks different. And I'll give you a little bit of time to do it. Question: Write the equivalent expression for the given expression: 3x+9. I don't see any number out front of the z.
Let us evaluate the expressions for some values of and. So, your problem is actually: 4t-1t+2. Now let us consider some expressions that include variables, say. How do you Combine the like terms to create an equivalent expression? BYJU'S online equivalent expression calculator tool makes the calculations and simplification faster and it displays the equivalent expression in a fraction of seconds. Explanation Detail steps. Now we'll just think it through. Two expressions are said to be equivalent if they have the same value irrespective of the value of the variable(s) in them. Simplify Calculator. Step 2: Now click the button "Submit" to get the equivalent expression. Or maybe you are upset because someone (a teacher or parent) is making you do this, and you just protest against others telling you what to do. Explain your answer. And that's OK, and there's nothing wrong with that. Step 2: Click the blue arrow to submit and see the result!
Only you can answer that, what is your attitude toward Math in general? And the coefficient on this subtracting the 2x, the coefficient here is negative 2, and we had to add the coefficients. There's not some fancy algebraic magic going on here. So i'm confused with this question: Combine the like terms to create an equivalent expression. Example 2: Use the Distributive Law to expand the first expression. Can we actually combine terms like that? That is, the expressions are equivalent except when. Well you are just add the X's to the numbers like this (the first number is the coefficient btw)2x +4X = whatever the answer would be. Still have questions? I dont see any 1 inside the question(4 votes). Combine the 2 terms containing "t" by subtracting their coefficients and you get 3t+2. And it said the answer is this: 4t-t+2=(4-1)t+2.
The expression can be rewritten as. But I really want to emphasize the intuition here. That is, they are equivalent expressions. Gauth Tutor Solution. We have a hairy-looking expression here. Step 1: Enter the expression you want to simplify into the editor.
So the equation becomes this: -4q +8q +10. Well, I'm going to be left with 3 x's. And so you could just say, oh, I had to just add the coefficients. How to Use the Equivalent Expression Calculator? Khan has a lot of good content that help a lot of other people, so you have to figure why it does not help you. All these expressions have the same value, whenever the same value is substituted for. If I've got 8 of something and I take away 1 of them, I'm going to have 7 of that something.
Take 3 outside from the expression, we get, = 3(x+3), which is called the equivalent expression. Here is one perspective on this Ted Talk - "Why is X the unknown, (12 votes). Grade 12 · 2022-01-02. What is an Algebraic Expression? When, the expression is not defined. Enjoy live Q&A or pic answer. Consider the expressions and. Created by Sal Khan. Crop a question and search for answer. We can't think about merging the x's and the y's, at least not in any simple way right now, because that, frankly, wouldn't make any intuitive sense.
