Answer:
-14 ≤ x ≤ 20
Step-by-step explanation:
<u>Left inequality</u>:
2(3 -x) +5 ≤ 39
2(3 -x) ≤ 34 . . . . . subtract 5
3 -x ≤ 17 . . . . . . . divide by 2
3 -17 ≤ x . . . . . . . . add x-17
-14 ≤ x
__
<u>Right inequality</u>:
2(x -3) +5 ≤ 39
2(x -3) ≤ 34 . . . . . . subtract 5
x -3 ≤ 17 . . . . . . . . .divide by 2
x ≤ 20 . . . . . . . . . . add 3
__
The solution is ...
-14 ≤ x ≤ 20
