Answer:
x=9; JL= 23
Step-by-step explanation:
To find x:
If JL and KM are equivalent, then JL = KM. Substitute the equations and you get 2x+5 = 7x-40.
Put the similar terms on the same side by subtracting 2x from both sides and adding 40 to both sides. You will get 45=5x.
Get x alone by dividing both sides by 5 and you will get 9=x.
To find JL:
Substitute the x in 2x+5 (JL length equation) with 9. Your new equation will be 2(9) + 5.
2•9 = 18.
18+5=23
