allerySolve 5x - 3 < 3x + 1 where x is an integer.
A{0, 1, 2}
B{x ∈ ℤ : x ≤ 2}
C{... -2, -1, 0, 1, 2}
D{..., -2, -1, 0, 1}
Answer & Solution
Correct answer: D. {..., -2, -1, 0, 1}
5x - 3 < 3x + 1 → 2x < 4
→ x < 2. For integer x, solution set = {..., -2, -1, 0, 1}.
Note STRICT inequality excludes x = 2.
