Question

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

Answer 1

`-9h - 6 + 12h + 40 = 22 \\ \\ 3h - 6 + 40 = 22 \\ \\ 3h + 34 = 22 \\ \\ 3h = 22 - 34 \\ \\ 3h = -12 \\ \\ h = - (12)/(3) \\ \\ h = -4 \\ \\ Answer: \fbox {h = -4}`

Answer 2

Combine like terms.


`-9h + 12h = 3h`

-6 + 40 = 34


`34 + 3h = 22`

34+3h = 22
-34 -34

3h = -12


`(3h)/(3) = (-12)/(3)`

h = -12/3
h=-4

Answer:
`h = -4`
