Q16 of 51 Page 6

Solve


Multiplying both sides by 60 i. e., L. C. M. of 3, 4 and 5 we have

⇒ 20(2x-1) ≥ 15(3x-2) – 12(2-x)

⇒ 40x – 20 ≥ 45x – 30 – 24 + 12x

⇒ 40x – 20 ≥ 57x - 54

⇒ 40x – 20 + 20 ≥ 57x – 54 + 20

⇒ 40x ≥ 57x - 34

⇒ 40x – 57x ≥ 57x – 57x –34 (Rule 1)

⇒ -17x ≥ -34

⇒ x ≤ 2

Solution set = (-∞ , 2).
