What is the solution of 3 times the absolute value of x + 5 <= 6
I think the answer is x <=  3 and x >= 7
If I'm not right, could you tell me why?

3x+5<= 6
3x+15<= 6
15 15
3x <= 9
/3 /3
x <= 3
Yes, you are correct. 
Thank youI appreciate it I posted another could you just check it to make sure I got this concept.

3x+5 ≤ 6
x+5 ≤ 2
x+5 ≤ 2 AND x5 ≤ 2
x ≤ 3 AND x ≤ 7
x ≤ 3 AND x ≥ 7
7 ≤ x ≤ 3 
Thank you
