Answer:
x = -4
Step-by-step explanation:
-5x-4x-2 = -8x+2 is the only one with a solution.
-5x-4x-2 = -8x+2
-x-2 = 2
-x = 4
x = -4
For this case we must solve the following equation:

We apply distributive property on the right side of the equation:

We subtract 6y on both sides of the equation:

We subtract 6 from both sides of the equation:

Dividing by 6 on both sides of the equation:

So, the result is
