2y=75-3z
Subtract 3z from both sides.
\frac{2y}{2}=\frac{75-3z}{2}
Divide both sides by 2.
y=\frac{75-3z}{2}
Dividing by 2 undoes the multiplication by 2.
3z=75-2y
Subtract 2y from both sides.
\frac{3z}{3}=\frac{75-2y}{3}
Divide both sides by 3.
z=\frac{75-2y}{3}
Dividing by 3 undoes the multiplication by 3.
z=-\frac{2y}{3}+25
Divide 75-2y by 3.
