Find all real number x which satisfy the inequality \(\frac{1}{3}\) (x + 1) - 1 > \(\frac{1}{5}\)(x + 4)
Take Free Practice Test On 2026 JAMB UTME, Post UTME, WAEC SSCE, GCE, NECO SSCE
  • A X < 11
  • B X < -1
  • C X > 6
  • D X > 11
Correct Answer: Option D
Explanation:
\(\frac{1}{3}\) (x + 1) - 1 > \(\frac{1}{5}\)(x + 4) = \(\frac{x + 1}{3} - 1\) > \(\frac{x + 4}{5}\)

\(\frac{x + 1}{3} - \frac{x + 4}{5} -1\) > 0

= \(\frac{5x + 5 - 3x - 12}{15}\)

2x - 7 > 15

2x > 22 = x > 11
