5x=45+y
Add y to both sides.
5x=y+45
The equation is in standard form.
\frac{5x}{5}=\frac{y+45}{5}
Divide both sides by 5.
x=\frac{y+45}{5}
Dividing by 5 undoes the multiplication by 5.
x=\frac{y}{5}+9
Divide 45+y by 5.
-y=45-5x
Subtract 5x from both sides.
\frac{-y}{-1}=\frac{45-5x}{-1}
Divide both sides by -1.
y=\frac{45-5x}{-1}
Dividing by -1 undoes the multiplication by -1.
y=5x-45
Divide 45-5x by -1.
