Answer:
(0, 0)
(4, 16)
Explanation:


Using substitution, we can replace y in the second equation with 4x from the first equation.

Now, we can move all the x's to one side and complete the square to solve for x.

↓ adding 4 to both sides

↓ factoring the right side

↓ taking the square root of both sides


↓ adding 2 to both sides


Then, we can solve for y by plugging both x-values into the first equation.

Finally, we can form two ordered pairs that are the solutions to the system of equations.
