- 5m + 12 = - 9
subtract 12 from each side
- 5m + 12 - 12 = - 9 - 12
- 5m = - 21
divide both sides integers by - 5
(- 5/- 5)m = - 21/- 5
m = 21/5
-----------------------check in original equation
= 5(21/5) + 12 = - 9
- 105/5 + 12 = = 9
(now, 12 = 60/5 , so)
- 105/5 + 60/5 = - 9
- 45/5 = - 9
- 9 = - 9
