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?

3|x+5|<= 6

|3x+15|<= 6

-15 -15

|3x| <= -9

/3 /3

x <= -3

Yes, you are correct.

3|x+5| ≤ 6

|x+5| ≤ 2

x+5 ≤ 2 AND -x-5 ≤ 2

x ≤ -3 AND -x ≤ 7

x ≤ -3 AND x ≥ -7

-7 ≤ x ≤ -3
