61-90x=31
Swap sides so that all variable terms are on the left hand side.
-90x=31-61
Subtract 61 from both sides.
-90x=-30
Subtract 61 from 31 to get -30.
x=\frac{-30}{-90}
Divide both sides by -90.
x=\frac{1}{3}
Reduce the fraction \frac{-30}{-90} to lowest terms by extracting and canceling out -30.
