and JK=7. find x, KL, and JL.

Very confused , can you please show steps to working out the problem

**Steve**, Sunday, August 25, 2013 at 6:23pmJL is the whole length, so JK is half the length. So,

7+7 = 4x-2

4x = 16

x = 4

So, JL = 4*4-2 = 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.
