Question

BRAINLY CUP!!!! First to answer gets Brainliest and 50 points!

Answer 1

-np-4≤2(c-3)
-np-4≤2x-6
-np≤2x-2
-n≤(2x-2)/p
n≥-((2x-2)/p)

Answer 2

So your main goal is to get n by itself right? Well here is what you do.
-np - 4 ≤ 2(c- 3)
First distribute.
-np - 4 ≤ 2c - 6
Add 4 to both sides.
-np ≤ 2c - 2
Divide by -p.
When you divide or multiply a negative the sign switches.
n ≥ 2c + 2/p
I hope this helps love! :)
