12k-18m=4k-2m
Use the distributive property to multiply 6 by 2k-3m.
12k-18m-4k=-2m
Subtract 4k from both sides.
8k-18m=-2m
Combine 12k and -4k to get 8k.
8k=-2m+18m
Add 18m to both sides.
8k=16m
Combine -2m and 18m to get 16m.
\frac{8k}{8}=\frac{16m}{8}
Divide both sides by 8.
k=\frac{16m}{8}
Dividing by 8 undoes the multiplication by 8.
k=2m
Divide 16m by 8.
12k-18m=4k-2m
Use the distributive property to multiply 6 by 2k-3m.
12k-18m+2m=4k
Add 2m to both sides.
12k-16m=4k
Combine -18m and 2m to get -16m.
-16m=4k-12k
Subtract 12k from both sides.
-16m=-8k
Combine 4k and -12k to get -8k.
\frac{-16m}{-16}=-\frac{8k}{-16}
Divide both sides by -16.
m=-\frac{8k}{-16}
Dividing by -16 undoes the multiplication by -16.
m=\frac{k}{2}
Divide -8k by -16.
