Answer:
h = -4
Step-by-step explanation:
Step 1: Distribute
-3h - 15 + 2 = 4h + 24 - 9
Step 2: Isolate x's
-15 + 2 = 3h + 4h + 24 - 9
-15 + 2 -24 + 9 = 3h + 4h
Step 3: Combine like terms
-28 = 7h
Step 4: Divide both sides by 7
h = -4
Alternatively, you can guess and check by plugging in each solution into the calc and seeing if it is correct or not.
