Question

Solve the compound inequality: 3x ≤ 18 AND x + 4 > 2

Answer 1

3x ≤ 18

x ≤ 18/3

x≤ 6

x + 4 > 2

x > 2 -4

x > - 2

Then - 2 < x ≤ 6

Answer: <=6

Answer 2

There must be a mistake in your question:
If 3 x ≤ 9, then : x ≤ 3  and : 
x + 4 > 2
x > 2 - 4
x > - 2
Answer: D) 
Solution set :  - 2 < x ≤ 3
