- 9h - 6+ 12h + 40 =22combine like terms
3h+34=22 subtract 34 from each side
3h=-12 divide by 3
h=-4
c. h = -4
is correct

-9h - 6 + 12h + 40 = 22
-6 + 3h + 40 = 22
3h + 40 = 28
3h = -12
h = -4

- 9h - 6+ 12h + 40 =22
3h + 34 = 22
3h = 22 - 34
3h = -12
h = -12 : 3
h = -4
Solution is c) -4.

First: combine "like" terms > combine "h variables:
-9h + 12h - 6 + 40 = 22
3h + 34 = 22
Second: subtract 34 from both sides > opposite side means opposite sign
3h + 34 - 34 = 22 - 34
3h = -12
Third: solve for "h" by keeping it on one side > divide both sides by 3
3h/3 = -12/3
h = -4

the answer is -4.
-9h-6+12h++40=22
add -9h +12h
-6+3h+40=22
add -6+40
3h+34=22
now minus -34 from 22
3h = -12
h = -4

Combine h's together to simplify.
-9h-6+12h+40=22
3h-6+40=22
Simplfy as much as possible
3h+34=22
Solve
3h+34-34=22-34
3h=-12
h=-4
The answer is c.

-9h - 6 + 12h + 40 = 22
3h + 34 = 22 (Subtract 34 from both sides)
3h = -12 (Divide both sides by 3)
h = -4
The correct answer is c, h = -4
