Hello!
9(x - 6) = 8(x + 6)
The first step to take here is to apply the Distributive Property, which is
a(b + c) = ab + ac.
9(x - 6) = 8(x + 6)
9x - 54 = 8x + 48
After this, you want to begin to eliminate terms to ultimately isolate x; you can subtract 8x from both sides first:
9x - 54 = 8x + 48
x - 54 = 48
Finally, add 54 to both sides to get x by itself:
x - 54 = 48
x = 102
Answer:
x = 102
