5x=21+3y
Add 3y to both sides.
5x=3y+21
The equation is in standard form.
\frac{5x}{5}=\frac{3y+21}{5}
Divide both sides by 5.
x=\frac{3y+21}{5}
Dividing by 5 undoes the multiplication by 5.
-3y=21-5x
Subtract 5x from both sides.
\frac{-3y}{-3}=\frac{21-5x}{-3}
Divide both sides by -3.
y=\frac{21-5x}{-3}
Dividing by -3 undoes the multiplication by -3.
y=\frac{5x}{3}-7
Divide 21-5x by -3.
