Which is the solution of the inequality ( \frac{3x-2}{5}-\frac{x+4}{2}\geq -1 )?

Answer and explanation

Correct answer: \(x \geq 14\)

Multiplying both sides by the positive number 10 does not change the inequality sign: \(6x-4-5x-20\geq -10\). Thus, \(x-24\geq -10\), so \(x\geq 14\). The option \(x>14\) is incorrect because it excludes 14, and \(x=14\) satisfies the original inequality. Exam tip: Multiply by the LCM of the denominators to solve fractional inequalities efficiently.
