Firstly, u need to prove the two triangle congurent.Here, the two triangle are congurent via AAS axiom (angle M=angle k, angle KLJ=angle JLM and JL is the common side)

Now,

use a fact of congurent triangle which says the side opposite to the equal angle is also equal and equate the sides JK and JM.

on equating,

x+5=2x-7

therefore, x=12
