270-3x+300-6x=x
Multiply both sides of the equation by 3.
570-3x-6x=x
Add 270 and 300 to get 570.
570-9x=x
Combine -3x and -6x to get -9x.
570-9x-x=0
Subtract x from both sides.
570-10x=0
Combine -9x and -x to get -10x.
-10x=-570
Subtract 570 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-570}{-10}
Divide both sides by -10.
x=57
Divide -570 by -10 to get 57.
