Verified Answer :

You add -2m to the other side and add 9 to the other side as well and then add 2m +16m= 18m and then divide 9 by 18

-2m = 16m - 9

First, take '16m' from both sides.
\(-2m - 16m = -9\)
Second, add '-2m - 16m' to get '-18m'.
\(-18m = -9\)
Third, divide both sides by '-18'.
\(m = \frac{-9}{-18}\)
Fourth, change the fraction into a negative.
\(m = \frac{9}{18}\)
Fifth, find the GCF of 9 and 18.
The GCF is 9.
Sixth,  divide the numerator by the GCF.
\(9\) ÷ \(9 = 1\)
Seventh, divide the denominator by the GCF.
\(18\) ÷ \(9 = 2\)
Eighth, rewrite the fraction in simplest form.
\(m = \frac{1}{2}\)

Answer as fraction: \(m = \frac{1}{2}\)
Answer as decimal: \(m = 0.5\)
