    The solution to the system is the intersection points of the graphs of those functions. First, you have to find the x-coordinate of the intersection point. Substitute the equation 1 in equation 2 using the y-variable, so it will be like this: \(\sf x^2-5x+15 = -x+10\) Now simplify that equation and tell me what you will get for the x value.
