Answer:

(3, 0)

Step-by-step explanation:

As the first step in solving this system, substitute x - 3 for y in y= x^2 - 5x+ 6.  This temporarily eliminates y and gives us the equation in x  x - 3 = x^2 - 5x + 6, which simplifies to x^2 - 6x + 9, whose roots are {3, 3}.  When x = 3,  y = 0.  Thus, the solution is (3, 0).
