9x=-13-4y
Subtract 4y from both sides.
9x=-4y-13
The equation is in standard form.
\frac{9x}{9}=\frac{-4y-13}{9}
Divide both sides by 9.
x=\frac{-4y-13}{9}
Dividing by 9 undoes the multiplication by 9.
4y=-13-9x
Subtract 9x from both sides.
4y=-9x-13
The equation is in standard form.
\frac{4y}{4}=\frac{-9x-13}{4}
Divide both sides by 4.
y=\frac{-9x-13}{4}
Dividing by 4 undoes the multiplication by 4.
