Answer:
(4,7), (-1,12)
Explanation:
I will solve using elimination by subtracting one equation from the other.
y = x² - 4x + 7
- y = -x + 11
__________
0 = x² - 3x -4
0 = (x - 4)(x + 1)
x = 4, x = -1
We can plug in these values to get the corresponding y -values.
The solutions should be : (4,7), (-1,12)
