Answer:
JK = 10 units
KL = 5 units
Explanation:
JK + KL = JL
When doing these types of problems, always try to solve the unknown variable before you solve the equations.
Solve for x:
-x + 15 + 2x - 5 = 15
x + 10 = 15
x = 5
Now plug in the x into the 2 equations,
JK = - (5) + 15
JK = 10 units
KL = 2(5) -5
KL = 10 - 5
KL - 5 units
i hope this helps you! :D
