Answer:
x = -3
Explanation:
15 = 5
x-6 x (I cannot draw the fraction line, but it looks like it)
cross multiple and you get, 15x = 5(x-6)
distribute the 5 on the right side of equation, 15x = 5x-30
combine like terms by subtracting 5x from both sides (cause what you do to one side, you do to the other!!!), 15x-5x = 5x-5x-30
10x = -30
divide by 10 (again, do it to both sides), x/10 = -30/10
solve for x, x = -3
