2x=20+6y
Add 6y to both sides.
2x=6y+20
The equation is in standard form.
\frac{2x}{2}=\frac{6y+20}{2}
Divide both sides by 2.
x=\frac{6y+20}{2}
Dividing by 2 undoes the multiplication by 2.
x=3y+10
Divide 20+6y by 2.
-6y=20-2x
Subtract 2x from both sides.
\frac{-6y}{-6}=\frac{20-2x}{-6}
Divide both sides by -6.
y=\frac{20-2x}{-6}
Dividing by -6 undoes the multiplication by -6.
y=\frac{x-10}{3}
Divide 20-2x by -6.
