y=15x-825+55
Use the distributive property to multiply 15 by x-55.
y=15x-770
Add -825 and 55 to get -770.
15x-770=y
Swap sides so that all variable terms are on the left hand side.
15x=y+770
Add 770 to both sides.
\frac{15x}{15}=\frac{y+770}{15}
Divide both sides by 15.
x=\frac{y+770}{15}
Dividing by 15 undoes the multiplication by 15.
x=\frac{y}{15}+\frac{154}{3}
Divide y+770 by 15.
y=15x-825+55
Use the distributive property to multiply 15 by x-55.
y=15x-770
