5x=40-4y
Subtract 4y from both sides.
\frac{5x}{5}=\frac{40-4y}{5}
Divide both sides by 5.
x=\frac{40-4y}{5}
Dividing by 5 undoes the multiplication by 5.
x=-\frac{4y}{5}+8
Divide 40-4y by 5.
4y=40-5x
Subtract 5x from both sides.
\frac{4y}{4}=\frac{40-5x}{4}
Divide both sides by 4.
y=\frac{40-5x}{4}
Dividing by 4 undoes the multiplication by 4.
y=-\frac{5x}{4}+10
Divide 40-5x by 4.
