K is the midpoint of JL JL=4x2
and JK=7. find x, KL, and JL.
Very confused , can you please show steps to working out the problem

JL is the whole length, so JK is half the length. So,
7+7 = 4x2
4x = 16
x = 4
So, JL = 4*42 = 14
JK = KL = 7
Actually, since they told us that JK=7, we knew right away that JL was 14, since JK was half of JL. All that nonsense about x and stuff was superfluous. 
thank you so much steve
