Question

Solve this equation: –9h – 6 + 12h + 40 = 22.

Answer 1

Answer: h = -4

Step-by-step explanation:

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

-9h+12h=22+6-40 "collect all unknown values in a side and collect numbers in other side "

"Don't forget to Change signs"

3h= -12

3h/3 = -12/3 "dividing by 3 in both sides"

h= -4

Answer 2

$-9h-6+12h+40=22\qquad\text{combine like terms}\\\\(-9h+12h)+(-6+40)=22\\\\3h+34=22\qquad\text{subtract 34 from both sides}\\\\3h=-12\qquad\text{divide both sides by 3}\\\\\boxed{h=-4}$
