Answer:

a=4

Step-by-step explanation:

8x-8+3ax=5ax-2a

Get all the terms with a on the right side

Subtract 3ax from each side

8x-8+3ax-3ax=5ax-3ax-2a

8x-8 = 2ax -2a

Factor out an 8 on the left and 2a on the right

8(x-1)  = 2a*(x-1)

Divide by (x-1) on both sides

8(x-1)/(x-1)  = 2a*(x-1)/(x-1)

8 = 2a

Divide by 2

8/2 =2a/2

4 =a
