Answer:
C) 20x + 25y = 65
−20x + 16y = 64
Explanation:
These two systems are relatively proportionate to each other because the bottom equation was multiplied by −2, while the top equation was multiplied by 5 in order to get two additive-inverse coefficients to eliminate with their variables, which in this case are −20x and 20x. Additive inverses result in zero.
