Answer:
-5/12 ≤ x ≤ 4
Explanation:
This compound inequality can be written as two:
Solving these one at a time, we get ...
-5x -4 ≤ -6x
x - 4 ≤ 0 . . . . . add 6x
x ≤ 4 . . . . . . . . add 4
__
-6x ≤ 6x +5
0 ≤ 12x +5 . . . . add 6x
0 ≤ x + 5/12 . . . . . . divide by 12
-5/12 ≤ x . . . . . . subtract 5/12
Then the solution is ...
-5/12 ≤ x ≤ 4
