2520-5x=9x
Multiply both sides of the equation by 45, the least common multiple of 9,5.
2520-5x-9x=0
Subtract 9x from both sides.
2520-14x=0
Combine -5x and -9x to get -14x.
-14x=-2520
Subtract 2520 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-2520}{-14}
Divide both sides by -14.
x=180
Divide -2520 by -14 to get 180.
