4x=-11+9y
Add 9y to both sides.
4x=9y-11
The equation is in standard form.
\frac{4x}{4}=\frac{9y-11}{4}
Divide both sides by 4.
x=\frac{9y-11}{4}
Dividing by 4 undoes the multiplication by 4.
-9y=-11-4x
Subtract 4x from both sides.
-9y=-4x-11
The equation is in standard form.
\frac{-9y}{-9}=\frac{-4x-11}{-9}
Divide both sides by -9.
y=\frac{-4x-11}{-9}
Dividing by -9 undoes the multiplication by -9.
y=\frac{4x+11}{9}
Divide -11-4x by -9.
