JK+KL=JL
(5x-8)+7x-12=10x-2
(add common terms together)
12x-20=10x-2
(get the term with x alone on one side of the equation)
2x=18
(divide by 2 to get x alone)
x=9

Find KL:
KL=7(9)-12
KL=51

The value for KL is 51.

Given that,

  • The JL = 10x - 2.
  • The JK = 5x - 8.
  • And, the KL = 7x - 12.

Now based on this we can say

JK + KL = JL

5x - 8 + 7x - 12 = 10x - 2

12x - 20 = 10x - 2

12x  - 10x = -2 + 20

2x = 18

x = 9

Now put the value of x in the KL i.e.

= 7x - 12

= 7(9) - 12

= 63 - 12

= 51

Therefore we can conclude that the value for KL is 51.
