Solution

To solve the system of equations, we need to set the two equations equal to each other since they both equal x.

So, we have:

y^2 + 4y - 5 = 0

This is a quadratic equation, which we can solve using the quadratic formula: y = [-b ± sqrt(b^2 - 4ac)] / (2a)

In this equation, a = 1, b = 4, and c = -5.

Substituting these values into the quadratic formula gives:

y = [-4 ± sqrt((4)^2 - 41(-5))] / (2*1) y = [-4 ± sqrt(16 + 20)] / 2 y = [-4 ± sqrt(36)] / 2 y = [-4 ± 6] / 2

This gives us two solutions: y = 1 and y = -5.

Substituting y = 1 into the equation x = y^2 + 4y - 5 gives x = 0.

Substituting y = -5 into the equation x = y^2 + 4y - 5 also gives x = 0.

So, the solutions to the system of equations are (0, 1) and (0, -5), which corresponds to answer choice c.
