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
