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
Positive 3. Absolute values are never negative, they are either 0 or a positive. so -3 would be +3
28 should be added to make it a sub of zero
-2x+6y=6
-7x+8y=-5
2(7x+8y=-5)
-7(-2x+6y=6)
Distribute
14x+16y=-10
14x-42y=-42
eliminate
-26y=-32
divide
y=1.2
-2x+6(1.2)=6
-2x+7.4=6
subtract 7.4 on both sides
-2x=-1.4
divide
x=0.7
I believe this is right
