40x=2900-15y
Subtract 15y from both sides.
\frac{40x}{40}=\frac{2900-15y}{40}
Divide both sides by 40.
x=\frac{2900-15y}{40}
Dividing by 40 undoes the multiplication by 40.
x=-\frac{3y}{8}+\frac{145}{2}
Divide 2900-15y by 40.
15y=2900-40x
Subtract 40x from both sides.
\frac{15y}{15}=\frac{2900-40x}{15}
Divide both sides by 15.
y=\frac{2900-40x}{15}
Dividing by 15 undoes the multiplication by 15.
y=\frac{580-8x}{3}
Divide 2900-40x by 15.
