9x=-4-7y
Subtract 7y from both sides.
9x=-7y-4
The equation is in standard form.
\frac{9x}{9}=\frac{-7y-4}{9}
Divide both sides by 9.
x=\frac{-7y-4}{9}
Dividing by 9 undoes the multiplication by 9.
7y=-4-9x
Subtract 9x from both sides.
7y=-9x-4
The equation is in standard form.
\frac{7y}{7}=\frac{-9x-4}{7}
Divide both sides by 7.
y=\frac{-9x-4}{7}
Dividing by 7 undoes the multiplication by 7.
