4x=-7+3y
Add 3y to both sides.
4x=3y-7
The equation is in standard form.
\frac{4x}{4}=\frac{3y-7}{4}
Divide both sides by 4.
x=\frac{3y-7}{4}
Dividing by 4 undoes the multiplication by 4.
-3y=-7-4x
Subtract 4x from both sides.
-3y=-4x-7
The equation is in standard form.
\frac{-3y}{-3}=\frac{-4x-7}{-3}
Divide both sides by -3.
y=\frac{-4x-7}{-3}
Dividing by -3 undoes the multiplication by -3.
y=\frac{4x+7}{3}
Divide -7-4x by -3.
