Question

Solve for m.
-4m + 15 = -9m - 15
m

Answer 1

m = - 6

Explanation:

given the equation

- 4m + 15 = - 9m - 15 ( add 9m to both sides )

- 4m + 9m + 15 = - 9m + 9m - 15 ( simplify both sides )

5m + 15 = - 15 ( subtract 15 from both sides )

5m + 15 - 15 = - 15 - 15 ( simplify both sides )

5m = - 30 ( divide both sides by 5 )

`(5)/(5)` m =
`(-30)/(5)` , then

m = - 6
