-30x+90+18x=900
Multiply both sides of the equation by 10.
-12x+90=900
Combine -30x and 18x to get -12x.
-12x=900-90
Subtract 90 from both sides.
-12x=810
Subtract 90 from 900 to get 810.
x=\frac{810}{-12}
Divide both sides by -12.
x=-\frac{135}{2}
Reduce the fraction \frac{810}{-12} to lowest terms by extracting and canceling out 6.
