y=9-24x+42
Calculate 3 to the power of 2 and get 9.
y=51-24x
Add 9 and 42 to get 51.
51-24x=y
Swap sides so that all variable terms are on the left hand side.
-24x=y-51
Subtract 51 from both sides.
\frac{-24x}{-24}=\frac{y-51}{-24}
Divide both sides by -24.
x=\frac{y-51}{-24}
Dividing by -24 undoes the multiplication by -24.
x=-\frac{y}{24}+\frac{17}{8}
Divide y-51 by -24.
y=9-24x+42
Calculate 3 to the power of 2 and get 9.
y=51-24x
Add 9 and 42 to get 51.
