This question was addressed to me in an online interview.

I need to ask this question from Reduce the Given Linear Equations to a Simpler Form topic in division Linear Equations in One Variable of Mathematics – Class 8

Answer 1

The correct option is (b) \(\frac{7}{2}\)

Explanation: 11x – 2 = 7x + 12

∴ 11x – 7x = 12 + 2

∴ 4x = 14

∴ x = \(\frac{14}{4} = \frac{7}{2}\).
