-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.
x=\frac{7-3y}{4}
Divide -7+3y by -4.
-3y=-7+4x
Add 4x to 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{7-4x}{3}
Divide -7+4x by -3.
