                                                        COMPROBACION

X = 1                                                2(1) + 3(-1)  + (2) = 2 -3 +2 = 4 – 3 = 1

Y = -1                                                3(1) – 2(-1) – 4(2) = 3 + 2 - 8 = 5 – 8 = -3

Z = 2                                                5(1) – (-1) – (2) = 5 +1 -2 = 4
