Answer:
(2,5)
Step-by-step explanation:
The solution of the system is the order pair that satisfies both equations.
The first given equation is:
x = y - 3
This can be written as:
y = x+3 .......> I
The second given equation is:
x^2 - 6x + 13 = y .........> II
Substitute with I in II and solve for x as follows:
x^2 - 6x + 13 = y
x^2 - 6x + 13 = x + 3
x^2 - 6x + 13 - x - 3 = 0
x^2 - 7x + 10 = 0
(x-5)(x-2) = 0
either x = 5
or x = 2
Substitute with x in equation I to get y as follows:
at x = 5 : y = 5+3 = 8...> first solution is (5,8)
at x = 2 : y = 2+3 = 5...> second solution is (2,5)
