JK and KL make up line JL.

JL = 2x + 8, JK = 2x - 2, KL = x - 9

If JK and KL make up line JL:

JK + KL = JL

We are solving for KL, so isolate it.

JK - JK + KL = JL - JK
KL = JL - JK
x - 9 = 2x + 8 - (2x - 2)
x - 9 = 2x - 2x + 8 + 2
x - 9 = 10

Often times, we would solve for x, but considering x - 9 is what we wanted the solution to anyway, we don't need to bother solving for x.

KL = 10
