Answer:
JL = 54
Step-by-step explanation:
When K is the midpoint of JL, we have ...
JK + KL = JL
and
JK = KL
Using this latter equation, we can substitute the given expressions to get
(8x+11) = (14x -1)
12 = 6x . . . . . . . . . add 1-8x to both sides
2 = x
Using this, we can find JL.
JK = 8x +11 = 8(2) +11 = 27
KL = JK = 27
JL = JL +KL = 27 +27
JL = 54
