Question

When the equation \(\frac{12x}{2} + \frac{6x}{5}\) = 0 is simplified the solution of the equation would be?

(a) x=0

(b) x=1

(c) x-1=0

(d) x+1=0

This question was addressed to me by my school principal while I was bunking the class.

Origin of the question is Reduce the Given Linear Equations to a Simpler Form topic in chapter Linear Equations in One Variable of Mathematics – Class 8

Answer 1

Right choice is (a) x=0

The best I can explain: \(\frac{12x}{2} + \frac{6x}{5}\) = 0

∴ \(\frac{5*12x}{2*5} + \frac{2*6x}{5*2)}\) = 0

∴ 60x+12x=0

∴ 72x=0

∴ x=0.
