-3x-7=3y
Add 3y to both sides. Anything plus zero gives itself.
-3x=3y+7
Add 7 to both sides.
\frac{-3x}{-3}=\frac{3y+7}{-3}
Divide both sides by -3.
x=\frac{3y+7}{-3}
Dividing by -3 undoes the multiplication by -3.
x=-y-\frac{7}{3}
Divide 3y+7 by -3.
-3y-7=3x
Add 3x to both sides. Anything plus zero gives itself.
-3y=3x+7
Add 7 to both sides.
\frac{-3y}{-3}=\frac{3x+7}{-3}
Divide both sides by -3.
y=\frac{3x+7}{-3}
Dividing by -3 undoes the multiplication by -3.
y=-x-\frac{7}{3}
Divide 3x+7 by -3.
