4x+4y=144
Combine 3x and x to get 4x.
4x=144-4y
Subtract 4y from both sides.
\frac{4x}{4}=\frac{144-4y}{4}
Divide both sides by 4.
x=\frac{144-4y}{4}
Dividing by 4 undoes the multiplication by 4.
x=36-y
Divide 144-4y by 4.
4x+4y=144
Combine 3x and x to get 4x.
4y=144-4x
Subtract 4x from both sides.
\frac{4y}{4}=\frac{144-4x}{4}
Divide both sides by 4.
y=\frac{144-4x}{4}
Dividing by 4 undoes the multiplication by 4.
y=36-x
Divide 144-4x by 4.
