Explanation:
The slopes of y = 2x+6 and y = -x+5 are m = 2 and m = -1 respectively.
Refer to the y = mx+b form.
Since the slopes are different, this means that the lines aren't parallel and they don't overlap perfectly either. The lines instead form some kind of X shape to cross at exactly one point. This intersection point is the single solution to the system of equations.
