Hello Again! The answer would be C. (8,11)
To confirm we will plug the numbers x = 8, Y = 11
------------------------
2x - 5 = y
(2 x 8) - 5 = 11
16 - 5 = 11
------------------------
y = x + 3
11 = 8 + 3
------------------------
So now you can determine that the answer would be (8,11)

<h3>How to solve the simultaneous equation?</h3>
Given:
x-y=k.............(eq i)
2x²+y²-15..............(eq ii)
We would make y the subject formula in eq ii
2x²+y²-15= 0
2x² + y²= 15
y²= 15-2x²
y=
...........(eq iii)
Substitute the value of y into eq i
x-(
= k
x- (
= k
k=

Step-by-step explanation:
you move -5y to the other side.
25=-5y-3xsubtract 25 both sides
0=-5y-3x-25then add 5y both sides
5y=-3x-25divide 5 both sides
y=-3/5x-5
