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