Answer:
The solution of the system of equations is the point ![(3,-1)](https://tex.z-dn.net/?f=%283%2C-1%29)
![x=3,y=-1](https://tex.z-dn.net/?f=x%3D3%2Cy%3D-1)
Step-by-step explanation:
we have
------> equation A
------> equation B
Using a graphing tool
we know that
The solution of the system of equations is the intersection point both graphs
The intersection point is ![(3,-1)](https://tex.z-dn.net/?f=%283%2C-1%29)
see the attached figure
therefore
The solution of the system of equations is the point ![(3,-1)](https://tex.z-dn.net/?f=%283%2C-1%29)
7 is half of 14 that's the answer
Subtract the totals and you get 223. Then divide 223/1538=14.5
