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