2y+3x=270
Swap sides so that all variable terms are on the left hand side.
3x=270-2y
Subtract 2y from both sides.
\frac{3x}{3}=\frac{270-2y}{3}
Divide both sides by 3.
x=\frac{270-2y}{3}
Dividing by 3 undoes the multiplication by 3.
x=-\frac{2y}{3}+90
Divide 270-2y by 3.
2y+3x=270
Swap sides so that all variable terms are on the left hand side.
2y=270-3x
Subtract 3x from both sides.
\frac{2y}{2}=\frac{270-3x}{2}
Divide both sides by 2.
y=\frac{270-3x}{2}
Dividing by 2 undoes the multiplication by 2.
y=-\frac{3x}{2}+135
Divide 270-3x by 2.
