Answer:
JL = 11 units
Step-by-step explanation:
Add the units between JK and KL together to get the answer for JL
Step 1. Subtract 4m from both sides
d - 4m = 7n
Step 2. Divide both sides by 7
d - 4m/7 = n
Step 3. Switch sides
n = d - 4m/7
Answer:
![a = \frac{49}{2}](https://tex.z-dn.net/?f=a%20%3D%20%5Cfrac%7B49%7D%7B2%7D)
![b = 18](https://tex.z-dn.net/?f=b%20%3D%2018)
Step-by-step explanation:
Lets focus on the third equation to find a:
50 - 2a = 1
Add 2a to both sides of the equation:
50 - 2a + 2a = 1 + 2a
50 = 1 + 2a
Subtract 1 from both sides of the equation:
50 - 1 = 1 + 2a - 1
49 = 2a
Divide both sides by 2:
![\frac{2a}{2} = \frac{49}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2a%7D%7B2%7D%20%3D%20%5Cfrac%7B49%7D%7B2%7D)
![a = \frac{49}{2}](https://tex.z-dn.net/?f=a%20%3D%20%5Cfrac%7B49%7D%7B2%7D)
Now substitute in the know a variable into the first equation:
![2a - 3b = -5](https://tex.z-dn.net/?f=2a%20-%203b%20%3D%20-5)
![49 - 3b = -5](https://tex.z-dn.net/?f=49%20-%203b%20%3D%20-5)
Add 3b to both sides:
![49 - 3b + 3b = -5 + 3b\\49 = -5 + 3b](https://tex.z-dn.net/?f=49%20-%203b%20%2B%203b%20%3D%20-5%20%2B%203b%5C%5C49%20%3D%20-5%20%2B%203b)
Add 5 to both sides:
![49 + 5 = -5 + 3b + 5](https://tex.z-dn.net/?f=49%20%2B%205%20%3D%20-5%20%2B%203b%20%2B%205)
54 = 3b
Divide both sides by 3:
![\frac{53}{3} = \frac{3b}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B53%7D%7B3%7D%20%3D%20%5Cfrac%7B3b%7D%7B3%7D)
![b = 18](https://tex.z-dn.net/?f=b%20%3D%2018)
c cannot be solved as there is no c variable.
Hope this helps!
