You can put this solution on YOUR website! Remember what you do to one side, you must do to the other to keep both sides equal.
6(x - 6) = x(16 - 7)
6x - 36 = 16x - 7x (Distributive property)
6x - 36 = 9x
6x - 36 +36 = 9x +36
6x + 0 = 9x +36
6x - 9x = 9x - 9x +36
6x - 9x = 9x - 9x +36
-3x = 0 + 36
-3x = 36
-3x * -1/3 = 36 * -1/3
-3x * -1/3 = 36 * -1/3
x * 1 = -12
x = -12
Substitute -12 back into the equation to make sure it is a solution.
