Mr. Brown is creating examples of systems of equations. He completes the steps to find the solution to the equation below. 5x + 2y = 8
-4(1.25x +0.5y = 2)

5x + 2y = 8
-5x - 2y = 8

0 = 0

Based on this work, what is the solution to the system?

(-4, -4)

(0, 0)

no solution

infinitely many solutions
