Answer:
x = 4, JL = 2
Step-by-step explanation:
Given that MN bisects JL at K , then
JK = KL , substitute values
x - 3 = 13 - 3x ( add 3x to both sides )
4x - 3 = 13 ( add 3 to both sides )
4x = 16 ( divide both sides by 4 )
x = 4
Thus
JL = JK + KL = x - 3 + 13 - 3x = 10 - 2x = 10 - 2(4) = 10 - 8 = 2
