WebSince both equations give y explicitly in terms of x, we can easily substitute either equation into the other one, to get x^2-5x-14 = x-7. Therefore, x^2-6x-7 = 0; (x-7) (x+1) = 0; x-7=0 or x+1=0; x=7 or x=-1. Since y=x-7, it follows that y=0 when x=7, and y=-8 when x=-1. So the solutions are the ordered pairs (7, 0) and (-1, -8).
