Q18 of 122 Page 15

Solve the following linear inequations in R

Given



⇒ 3(x – 2) ≤ 5x + 8


⇒ 3x – 6 ≤ 5x + 8


⇒ 3x – 6 + 6 ≤ 5x + 8 + 6


⇒ 3x ≤ 5x + 14


⇒ 5x + 14 ≥ 3x


⇒ 5x + 14 – 14 ≥ 3x – 14


⇒ 5x ≥ 3x – 14


⇒ 5x – 3x ≥ 3x – 14 – 3x


⇒ 2x ≥ –14



∴ x ≥ –7


Thus, the solution of the given inequation is [–7, ∞).
