A (k, - 2), L:3x+2y=k

Not sure how to solve this.

All numbers are whatever you want them to be except k, k is 14 so 8•14=112 112 subtract - 2 equals 114 Do not find out what L is or the k at the end and now that youre reading this I wanna tell you Im in 5th grade and I have no clue what Im talking about so good luck!
