2L=600-2w
Subtract 2w from both sides.
\frac{2L}{2}=\frac{600-2w}{2}
Divide both sides by 2.
L=\frac{600-2w}{2}
Dividing by 2 undoes the multiplication by 2.
L=300-w
Divide 600-2w by 2.
2w=600-2L
Subtract 2L from both sides.
\frac{2w}{2}=\frac{600-2L}{2}
Divide both sides by 2.
w=\frac{600-2L}{2}
Dividing by 2 undoes the multiplication by 2.
w=300-L
Divide 600-2L by 2.
