We first group the like terms
-9h + 12h - 6 + 40 = 22
We now make h the subject
-9h + 12h = 2 + 6 - 40
Evaluate
3h = -12
h = -12/3
h = -4

Explanation/steps

1) Combine like terms
3h + 34 = 22

2) subtract 34 from both sides of the equation
3h + 34 - 34 = 22 - 34
3h = -12

3) Divide 3 from both sides of the equation
3h/3 = -12/3
h = -4

Therefore, h = -4
h =
