7x=-50+3y
Add 3y to both sides.
7x=3y-50
The equation is in standard form.
\frac{7x}{7}=\frac{3y-50}{7}
Divide both sides by 7.
x=\frac{3y-50}{7}
Dividing by 7 undoes the multiplication by 7.
-3y=-50-7x
Subtract 7x from both sides.
-3y=-7x-50
The equation is in standard form.
\frac{-3y}{-3}=\frac{-7x-50}{-3}
Divide both sides by -3.
y=\frac{-7x-50}{-3}
Dividing by -3 undoes the multiplication by -3.
y=\frac{7x+50}{3}
Divide -50-7x by -3.
