y=-2\left(-9\right)-12x-3-12
Calculate 3 to the power of 2 and get 9.
y=18-12x-3-12
Multiply -2 and -9 to get 18.
y=15-12x-12
Subtract 3 from 18 to get 15.
y=3-12x
Subtract 12 from 15 to get 3.
3-12x=y
Swap sides so that all variable terms are on the left hand side.
-12x=y-3
Subtract 3 from both sides.
\frac{-12x}{-12}=\frac{y-3}{-12}
Divide both sides by -12.
x=\frac{y-3}{-12}
Dividing by -12 undoes the multiplication by -12.
x=-\frac{y}{12}+\frac{1}{4}
Divide y-3 by -12.
y=-2\left(-9\right)-12x-3-12
Calculate 3 to the power of 2 and get 9.
y=18-12x-3-12
Multiply -2 and -9 to get 18.
y=15-12x-12
Subtract 3 from 18 to get 15.
y=3-12x
Subtract 12 from 15 to get 3.
