20x-15x=12x-1680
Multiply both sides of the equation by 120, the least common multiple of 6,8,10.
5x=12x-1680
Combine 20x and -15x to get 5x.
5x-12x=-1680
Subtract 12x from both sides.
-7x=-1680
Combine 5x and -12x to get -7x.
x=\frac{-1680}{-7}
Divide both sides by -7.
x=240
Divide -1680 by -7 to get 240.
