What are the solutions of this system of equations?
the first three steps in determining the solution set of the
system of equations algebraically are shown.
y = x2 - x-3
y=-3x + 5
(-2, -1) and (4, 17)
(-2, 11) and (4, -7)
(2, -1) and (-4, 17)
(2, 11) and (-4,-7)
step
1

equation
x– x-3 = -3x +5
0 = x² + 2x - 8
0 = (x-2)(x+4)
