ANSWER
(-2,-1)
(3,14)
EXPLANATION
The given system is
![y = {x}^{2} + 2x - 1](https://tex.z-dn.net/?f=y%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20%2B%202x%20-%201)
![y - 3x = 5](https://tex.z-dn.net/?f=%20y%20-%203x%20%3D%205)
or
![y = 3x + 5](https://tex.z-dn.net/?f=y%20%3D%203x%20%2B%205)
Equate both of them:
![{x}^{2} + 2x - 1 = 3x + 5](https://tex.z-dn.net/?f=%7Bx%7D%5E%7B2%7D%20%20%2B%202x%20-%201%20%3D%203x%20%2B%205)
This implies that,
![{x}^{2} - x - 6 = 0](https://tex.z-dn.net/?f=%7Bx%7D%5E%7B2%7D%20%20%20-%20x%20-%206%20%3D%200)
![(x - 3)(x + 2) = 0](https://tex.z-dn.net/?f=%28x%20-%203%29%28x%20%2B%202%29%20%3D%200)
x=-2 or x=3
When x=-2, y=y=3(-2)+5=-1
(-2,-1) is a solution.
When x=3 , y=3(3)+5=14
(3,14) is also a solution.
