150x+1800=240x
Multiply 12 and 150 to get 1800.
150x+1800-240x=0
Subtract 240x from both sides.
-90x+1800=0
Combine 150x and -240x to get -90x.
-90x=-1800
Subtract 1800 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-1800}{-90}
Divide both sides by -90.
x=20
Divide -1800 by -90 to get 20.
