7x=-20-4y
Subtract 4y from both sides.
7x=-4y-20
The equation is in standard form.
\frac{7x}{7}=\frac{-4y-20}{7}
Divide both sides by 7.
x=\frac{-4y-20}{7}
Dividing by 7 undoes the multiplication by 7.
4y=-20-7x
Subtract 7x from both sides.
4y=-7x-20
The equation is in standard form.
\frac{4y}{4}=\frac{-7x-20}{4}
Divide both sides by 4.
y=\frac{-7x-20}{4}
Dividing by 4 undoes the multiplication by 4.
y=-\frac{7x}{4}-5
Divide -20-7x by 4.
