Answer:
![x = 2k + 1 \\ y = k - 1 \\ given](https://tex.z-dn.net/?f=x%20%3D%202k%20%2B%201%20%5C%5C%20y%20%3D%20k%20-%201%20%5C%5C%20given)
if u substitute the givens in the eqn we will get..
![2(2k + 1) - 2(k - 1) + 5 = 0 \\ 4k + 2 - (2k - 2) + 5 = 0 \\ 4k + 2 - 2k + 2 + 5 = 0 \\](https://tex.z-dn.net/?f=2%282k%20%2B%201%29%20-%202%28k%20-%201%29%20%2B%205%20%3D%200%20%5C%5C%204k%20%2B%202%20-%20%282k%20-%202%29%20%2B%205%20%3D%200%20%5C%5C%204k%20%2B%202%20-%202k%20%2B%202%20%2B%205%20%3D%200%20%5C%5C%20)
then collect like terms
![4k - 2k + 2 + 2 + 5 = 0 \\ 2k + 4 + 5 = 0 \\ 2k + 9 = 0](https://tex.z-dn.net/?f=4k%20-%202k%20%2B%202%20%2B%202%20%2B%205%20%3D%200%20%5C%5C%202k%20%2B%204%20%2B%205%20%3D%200%20%5C%5C%202k%20%2B%209%20%3D%200)
![2k = - 9 \\ k = \frac{ - 9}{2}](https://tex.z-dn.net/?f=2k%20%3D%20%20-%209%20%5C%5C%20k%20%3D%20%20%5Cfrac%7B%20-%209%7D%7B2%7D%20)
