Answer:
Option (a) is correct.
Explanation:
Given: Equation 11kx + 13kx = 6
We have to solve for x and choose the correct option from the given options.
Consider the given equation 11kx + 13kx = 6
Taking kx common, we have,
kx (11+13) = 6
Simplify, we have,
24kx = 6
Divide both side by 24, we have,

Simplify, we have,

Divide both side by k, we have,
Thus, Option (a) is correct.
