x=1-x_{0}
Subtract 11 from 12 to get 1.
1-x_{0}=x
Swap sides so that all variable terms are on the left hand side.
-x_{0}=x-1
Subtract 1 from both sides.
\frac{-x_{0}}{-1}=\frac{x-1}{-1}
Divide both sides by -1.
x_{0}=\frac{x-1}{-1}
Dividing by -1 undoes the multiplication by -1.
x_{0}=1-x
Divide x-1 by -1.
x=1-x_{0}
Subtract 11 from 12 to get 1.
