- 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
