5x+4y=28
Combine 3x and 2x to get 5x.
5x=28-4y
Subtract 4y from both sides.
\frac{5x}{5}=\frac{28-4y}{5}
Divide both sides by 5.
x=\frac{28-4y}{5}
Dividing by 5 undoes the multiplication by 5.
5x+4y=28
Combine 3x and 2x to get 5x.
4y=28-5x
Subtract 5x from both sides.
\frac{4y}{4}=\frac{28-5x}{4}
Divide both sides by 4.
y=\frac{28-5x}{4}
Dividing by 4 undoes the multiplication by 4.
y=-\frac{5x}{4}+7
Divide 28-5x by 4.
