1. 5h - 9 = -16 + 6h
4
7
-7
10***
2. 4x + 4 = 9x - 13
-8
-7
8
-3
3. Which of the following equations has an infinite number of solutions?
3x - 3 = -4x
2y + 4 - y = 16
7x + 5 = 4x + 5 + 3x ***
6y - 2 = 2(y - 1)
6. q - 12 ≥ -13
q ≥ 1
q ≥ -1
q ≥ 25
q ≥ -25
7. 12p < 96
p < 8
p < 108
p < 84
P < -8 (?)
So for ^this problem, wouldn't it be -8? I feel like it's a trick question because it's too easy.
8. g over -5 < -8
g < -23
g > -90
g > 90
g < 90
10. You have $59.95 in your wallet and you want to buy some new CD's. If the CD's are $11.99 each, how may CD's, X, can you buy? Write and solve an inequality.
I have very little knowledge on how to do these problems. I've looked back through the lessons, I've looked up videos online, I can't figure it out. I'm in online school so I can't just ask the teacher, the lesson is already overdue and if I were to email her, it's the end of the year when she's the busiest, so it would take a very long time for her to get back to me.
If I get a 90% or higher, my grade will go up and I'll be one step closer to getting into my dream school, so please help?

1. Subtract 5h from both sides and add 16 to both sides.
2.Add 13 and subtract 4x from both sides. Looks like there is a typo somewhere.
3. Don't know.
6. Add 12 to both sides.
7. Divide both sides by 12.
8. When multiplying/dividing inequalities by a negative number, the sign is reversed.
8. g/-5 < -8
Multiply by -5. Typos?
10. $11.99x ≤ $59.95
Solve for x.
