Question

-7x+2x= what as an equivalent expression?

Answer 1

-5x

Explanation:

First, determine which terms are alike.

Alike terms are numbers that have the same variable.

These numbers both have the same variable, (x) so just add the numbers:

-7 + 2 = -5

You got 5, so now just add back on the variable, (x), making your answer -5x.

Answer 2

-5x

Explanation:

-7x + 2x = -5x

An easier way to look at the problem:

2x - 7x = -5x
