Which of the following numbers is NOT a solution of the inequality 3x - 5 >= 4x - 3?
A-5
B-1
C-2
D-3
Answer & Solution
Correct answer: B. -1
Rearrange: 3x - 5 >= 4x - 3 -> -5 + 3 >= 4x - 3x -> -2 >= x, i.e. x <= -2. So a value is NOT a solution if x > -2. Among options: -1 > -2 (NOT a solution); -2, -3, -5 all satisfy. Answer: -1.
