2(x - 1) + 8 = 4x - 20

2x - 2 + 8 = 4x - 20

2x + 6 = 4x - 20

2x = 4x - 26

-2x = -26

The answer is x = 13.

Answer:

x = 13

Step-by-step explanation:

Distribute the 2

2x - 2 + 8 = 4x - 20

Isolate the variables to 1 side

-2x = -26

x = 13

Verification

2(13 - 1) + 8 = 4(13) - 20

26 - 2 + 8 = 52 - 20

32 = 32
