Asked question is from Solving Linear Equations with Variables on Both the Sides in chapter Linear Equations in One Variable of Mathematics – Class 8

Answer 1

The correct choice is (a) 2 and 3

Easy explanation: Let the common multiple be x.

∴ 2x + 3x = 5

∴ 5x = 5

∴ x = 1

Since, x = 1 the natural numbers are 2 and 3.
