Answer:

-15x + 7y = 83

Step-by-step explanation:

Mostly what I get is 0 because what i was taught was moving the constant to the left ( -83=0)  and by changing the signs (- +) but like there are different things in this problem I get from the root (-83/15,0) xeR is domain and range yeR so I say 0. I'm sorry if its wrong.
