Answer:
(1, 3) and (-3, -5)
Explanation:
Given the system of equations:

Since both are y-isolated equations, set the equation up equal each other:

Arrange the equation in quadratic:

Square root both sides and solve the rest:

Next, substitute two x-values in either of those two equations. I'll substitute them in the second equation.
When x = 1,

When x = -3,

Therefore, the solutions are (1, 3) and (-3, -5).
