y=600-20x+1x
Use the distributive property to multiply 20 by 30-x.
y=600-19x
Combine -20x and 1x to get -19x.
600-19x=y
Swap sides so that all variable terms are on the left hand side.
-19x=y-600
Subtract 600 from both sides.
\frac{-19x}{-19}=\frac{y-600}{-19}
Divide both sides by -19.
x=\frac{y-600}{-19}
Dividing by -19 undoes the multiplication by -19.
x=\frac{600-y}{19}
Divide y-600 by -19.
y=600-20x+1x
Use the distributive property to multiply 20 by 30-x.
y=600-19x
Combine -20x and 1x to get -19x.
