Question

Simplify the following expression by combining like terms:
-2 + 6x + 2 - 2x + 8 – 4z

Answer 1

Combine like terms.

-2+8+2= 8
6x-2x=4x
-4z

8+4x-4z

Answer 2

4x+8-4z

Explanation:

since two opposites add up to 0 , remove them from the equation(-2 and +2)

next you're going to collect like terms

6x-2x=4x

so your final answer is 4x+8-4z
