Linear Inequalities – Class XI – Exercise 6.1 [1 0 – 26]

Solve the given inequality for real x: 3(x-2)/5 ≤ 5(2-x)/3 Solution: The given inequality is 3(x-2)/5 ≤ 5(2-x)/3 ⇒ 3(x-2)/5 ≤ 5(2-x)/3 ⇒ 9(x-2) ≤25(2-x) ⇒ 9x – 18 ≤ 50 – 25x ⇒ 34x – 18 ≤ 50 ⇒ 34x ≤ 68 ⇒ 34x/34 ≤ 68/34 ⇒ x ≤ 2 Thus, all real numbers… Continue reading Linear Inequalities – Class XI – Exercise 6.1 [1 0 – 26]
