Answer is E I think let me cheat
ANSWER
The solution is
![(3,2)](https://tex.z-dn.net/?f=%283%2C2%29)
<u>EXPLANATION</u>
We were given the equations
![y=4x-10--(1)](https://tex.z-dn.net/?f=y%3D4x-10--%281%29)
and
![y=2----equation (2)](https://tex.z-dn.net/?f=y%3D2----equation%20%282%29)
This is a simultaneous equation in
and
.
But the coefficient of
in the second equation is zero. that is why it seems to be absent.
We solve these two equations simultaneously
by putting
in to equation (1).
Tis gives;
![2=4x-10](https://tex.z-dn.net/?f=2%3D4x-10)
We add 10 to both sides to get;
![12=4x](https://tex.z-dn.net/?f=12%3D4x)
we divide through by 4 to get
![3=x](https://tex.z-dn.net/?f=3%3Dx)
Hence the solution for the system is ![(3,2)](https://tex.z-dn.net/?f=%283%2C2%29)
The answer is A because if you divide 30 by 6 you get 5 and if you divide 48 by 6 you get 8, that is your ratio 5:8, I hope this helps!
