Answer: x=-42 and y=-73
Step-by-step explanation:
Given the system of equations:
.........[1]
.......[2]
Multiplying [1] by 4 we have
........[3]
........[4]
Subtracting [4] from [3]
![-4x+4x+4y-3y=-124+51](https://tex.z-dn.net/?f=-4x%2B4x%2B4y-3y%3D-124%2B51)
⇒ y=-73
Putting it in [1]
![-73-x=-31](https://tex.z-dn.net/?f=-73-x%3D-31)
Adding 73 both sides
![-73+73-x=-31+73](https://tex.z-dn.net/?f=-73%2B73-x%3D-31%2B73)
-x=42
Multiplying both sides by -1
x=-42
Answer:
x=12
Step-by-step explanation:
divide by 4 on both sides
Step 1:
meassure angle for group 0-19 that lives in Adley
Step 2:
divide this angle by 360. this is proportional of that group in total number of people in Adley
Repeat these steps for group 0-19 in Bridford.
Final solution can be found by multiplying the two solutions of step 2.
