Question

Solve: 12x-13=2x*(11-12).

(a) x+\(\frac{13}{14}\)=0

(b) x-\(\frac{14}{13}\)=0

(c) x=\(\frac{13}{14}\)

(d) x+\(\frac{14}{13}\)=0

I have been asked this question in an internship interview.

My query is from Reduce the Given Linear Equations to a Simpler Form topic in division Linear Equations in One Variable of Mathematics – Class 8

Answer 1

Right option is (c) x=\(\frac{13}{14}\)

Explanation: 12x-13=2x*(11-12)

∴ 12x-13=22x-24x

∴ 12x-13= -2x

∴ 14x=13

∴ x=\(\frac{13}{14}\).
