91+0.2x=10
Swap sides so that all variable terms are on the left hand side.
0.2x=10-91
Subtract 91 from both sides.
0.2x=-81
Subtract 91 from 10 to get -81.
x=\frac{-81}{0.2}
Divide both sides by 0.2.
x=\frac{-810}{2}
Expand \frac{-81}{0.2} by multiplying both numerator and the denominator by 10.
x=-405
Divide -810 by 2 to get -405.
