6L=9000-2m
Subtract 2m from both sides.
\frac{6L}{6}=\frac{9000-2m}{6}
Divide both sides by 6.
L=\frac{9000-2m}{6}
Dividing by 6 undoes the multiplication by 6.
L=-\frac{m}{3}+1500
Divide 9000-2m by 6.
2m=9000-6L
Subtract 6L from both sides.
\frac{2m}{2}=\frac{9000-6L}{2}
Divide both sides by 2.
m=\frac{9000-6L}{2}
Dividing by 2 undoes the multiplication by 2.
m=4500-3L
Divide 9000-6L by 2.
