3x=19-2z
Subtract 2z from both sides.
\frac{3x}{3}=\frac{19-2z}{3}
Divide both sides by 3.
x=\frac{19-2z}{3}
Dividing by 3 undoes the multiplication by 3.
2z=19-3x
Subtract 3x from both sides.
\frac{2z}{2}=\frac{19-3x}{2}
Divide both sides by 2.
z=\frac{19-3x}{2}
Dividing by 2 undoes the multiplication by 2.
