Question

How many solutions does the equation 4x + 8 = − 2 − 2 + 5x have?

Answer 1

Answer: only one 4x+8=-4+5x

4x-5x=8+4

-1x=12

x=-12

Explanation:

Answer 2

12 =x

There is one solution

Explanation:

4x + 8 = − 2 − 2 + 5x

Combine like terms

4x+8 = -4+5x

Subtract 4x from each side

4x-4x+8 = -4+5x-4x

8 = -4+x

Add 4 to each side

8+4 = -4+4+x

12 =x
