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

explain how you got your answer

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

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

when multiplying or dividing by a negative on both sides you have to flip the inequality sign. this rule only applies to multiplying or dividing by a negative number in inequality equations. this rule is really important.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
