Answer:

KL = 51

Step-by-step explanation:

1: Make an equation

[tex]10x -2 = 5x-8 + 7x -12[/tex]

the 10x is the JL line which is the whole line segment

2: start solving by getting all x to be on one side

[tex]10x-5x-7x = -8 -12 +2[/tex]

3: simplify

[tex]-2x = -18[/tex]

4: solve for x

[tex]x=9[/tex]

5: plug x back into KL

[tex]7(9)-12 = 51[/tex]
