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

solve for a

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
