8(c-9) = 6(2c-12)-4c

Okay let us solve it together.
Multiply out and expand the brackets.

8c -89 = 62c -612 -4c
8c -72 = 12c -72 -4c Re arrange by taking the cs to one side
8c -12c +4c = -72 + 72
0 = 0

For this kind of statement it means C can be any number, and it would satisfy the equation.
Cheers.
