n ≤ –3 and n ≤ 2
n ≥ –3 and n ≤ 4
n ≤ 1 and n ≤ 6
n ≥ 3 and n ≤ –2

Answer 1

If anyone can here's another question
Solve the open sentence. 6 < 3b OR 3b + 12 < 9
b < –1 OR b > –6
b < –1 OR b < 3
b < 2 OR b > –3
b > 2 OR b < –1

Answer 2

For the first one, we want to have n by itself. So what would you need to do?
P.S. next time ask this in the math section ;)
