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

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