7x=-13+9y
Add 9y to both sides.
7x=9y-13
The equation is in standard form.
\frac{7x}{7}=\frac{9y-13}{7}
Divide both sides by 7.
x=\frac{9y-13}{7}
Dividing by 7 undoes the multiplication by 7.
-9y=-13-7x
Subtract 7x from both sides.
-9y=-7x-13
The equation is in standard form.
\frac{-9y}{-9}=\frac{-7x-13}{-9}
Divide both sides by -9.
y=\frac{-7x-13}{-9}
Dividing by -9 undoes the multiplication by -9.
y=\frac{7x+13}{9}
Divide -13-7x by -9.
