Answer:
(3,10) and (-1,2) (Plato/Edmentum)
Step-by-step explanation:
In the second equation, the variable y is not isolated, so it’s probably easiest to use substitution here. Substitute the right side of the first equation into the second equation:
(x2 + 1) − 2x = 4
x2 − 2x + 1 − 4 = 0
x2 − 2x − 3 = 0
(x − 3)(x + 1) = 0
x = 3 or x = -1
Substitute these values back into the system to solve for y:
y = (3)2 + 1 = 10
y = (-1)2 + 1 = 2
So, the coordinate pairs (3,10) and (-1,2) are solutions to the system.
