Which example illustrates the associative property of addition for polynomials? [(2x2 + 5x) + (4x2 – 4x)] + 5x3 =
(2x2 + 5x) + [(4x2 – 4x) + 5x3]

[(2x2 + 5x) + (4x2 – 4x)] + 5x3 =
[(4x2 – 4x) + (2x2 + 5x)] + 5x3

(2x2 + 5x) + [(4x2 – 4x) + 5x3] =
(2x2 + 5x) + [5x3 + (4x2 – 4x)]

[(2x2 + 5x) + (4x2 – 4x)] + 5x3 =
[(5x + 2x2) + (–4x + 4x2)] + 5x3

2x minus y equals 6, x plus y equals negative 3
