Question

Solve this equation -9h - 6 + 12h + 40 = 22

Answer 1

$-9h - 6 + 12h + 40 = 22\\\\3h=-12\\\\h=-4$

Answer 2

-9h - 6 + 12h + 40 = 22

                                       combine like rooms

3h + 34  = 22

     -34     -34              subtract 34 from both sides

3 h         =  - 12

/3                 /3             divide both sides 3

h              =  -4
