যদি (a/b)x - 3 = (b/a)x - 5 হয়, তবে x এর মান কত?
Solution
Correct Answer: Option B
(a/b)x - 3 = (b/a)x - 5
⇒ (a/b) x - 3 × (a/b) x - 5 = 1
⇒(a/b) x - 3 + x -5 = 1
⇒ (a/b)2x - 8= (a/b)0
⇒ 2x - 8 = 0
⇒ 2x = 8
x =4
⇒ (a/b) x - 3 × (a/b) x - 5 = 1
⇒(a/b) x - 3 + x -5 = 1
⇒ (a/b)2x - 8= (a/b)0
⇒ 2x - 8 = 0
⇒ 2x = 8
x =4
