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