1. (3x – 8y – 2z) + (7x + 3y + z) =2?

1. (3x – 8y – 2z) + (7x + 3y + z) = 2. (4a – 2b – 5c) – (3a – 5b – 7c) = 3. (y3 – y) + (2y2 – 5y + 7) + (4y3 – 5y2 + 3y – 8) = 4. (16x2 – 7x – 8) – (6x2 – 3x + 6) = 5. (11a – b + c) + ( - 8a – c) = 6. (3x3 – 5x2 – 6x + 3) – ( 2x3 + 4x – 8) = 7. (8a2 – 6a3 + 4a) + (4a3 + a2 – 4a – 5) = 8. (10m – 12n + 4p – 1) – ( - 8m + 6n – 3p – 2) = 9. (2x – 7y – 3z + 6) + ( - 9x + 4z) + ( - x + 4y + z – 8) = 10. (8s2 – 5s + 7) – (5s2 – 3s + 2) = 20 puntos a quien me diga porfa.
