y=5x+15
Use the distributive property to multiply 5 by x+3.
5x+15=y
Swap sides so that all variable terms are on the left hand side.
5x=y-15
Subtract 15 from both sides.
\frac{5x}{5}=\frac{y-15}{5}
Divide both sides by 5.
x=\frac{y-15}{5}
Dividing by 5 undoes the multiplication by 5.
x=\frac{y}{5}-3
Divide y-15 by 5.
y=5x+15
Use the distributive property to multiply 5 by x+3.
