-2m = 16m - 9
First, take '16m' from both sides.
Second, add '-2m - 16m' to get '-18m'.
Third, divide both sides by '-18'.
Fourth, change the fraction into a negative.
Fifth, find the GCF of 9 and 18.
The GCF is 9.
Sixth, divide the numerator by the GCF.

÷
Seventh, divide the denominator by the GCF.

÷
Eighth, rewrite the fraction in simplest form.
