10x=20+5y
Add 5y to both sides.
10x=5y+20
The equation is in standard form.
\frac{10x}{10}=\frac{5y+20}{10}
Divide both sides by 10.
x=\frac{5y+20}{10}
Dividing by 10 undoes the multiplication by 10.
x=\frac{y}{2}+2
Divide 20+5y by 10.
-5y=20-10x
Subtract 10x from both sides.
\frac{-5y}{-5}=\frac{20-10x}{-5}
Divide both sides by -5.
y=\frac{20-10x}{-5}
Dividing by -5 undoes the multiplication by -5.
y=2x-4
Divide 20-10x by -5.
