Answer: See explanation
Explanation:
4x + 20x - 8 = -2 (-12x + 8)
Step 1
Distribute -2 to (-12x + 8)
4x + 20x - 8 = 24x - 16
Step 2
Combine 4x and 20x together
24x - 8 = 24x - 16
Step 3
Add 8 to both sides
24x = 24x - 8
Step 4
Subtract 24x from both sides
0 ≠ -8
That is incorrect so it's not a solution
