Answer:
(-∞, -1/3) U (3, ∞)
Explanation:
The given inequality is equivalent to two inequalities (joined with OR).
-(3x -4) +3 ≥ 8
-3x +7 ≥ 8 . . . . . . eliminate parentheses
-3x ≥ 1 . . . . . . . subtract 7
x ≤ -1/3 . . . . . divide by 3
3x -4 +3 ≥ 8
3x ≥ 9 . . . . . add 1
x ≥ 3 . . . . . . divide by 3
Then the solution to the inequality is the union of these intervals:
x ∈ (-∞, -1/3) ∪ (3, ∞)
