Question

Which is a correct first step for solving this equation? +7=2+5−4

Answer 1

C (Bottom left)

Explanation:

2x and 4x are like terms, because they both have a coefficient of "x".

2x-4x = -2x, so c is the right answer (or bottom right)

Answer 2

The correct answer is x + 7 = -2x + 5

Explanation:

This is because you combine the like terms, 2x and -4x, which is equal to -2x.
