Answer (1)
Answer:1. 3a + 4b + 3a - 5b = 6a - b 2. a^2 + 7 - 3a^2 + 8a^2 + 15 = 6a^2 + 22 3. 3x + 4x + y - x + 8 + 5x = 11x + y + 8 4. -11 + x^2 + 3 - 25x^2 - 12x^2 = -36x^2 - 8 5. axy - x + y + 7x + 12xy - x + y = 13xy + 5x + 2y 6. 3x^2 + 5x + 2x^2 - 9x + 15 + x^2 = 6x^2 - 4x + 15 7. 5x^3 + x - 4x^2 + 8x - 5x + 11x^2 + 3 - x^3 = 4x^3 + 7x^2 + 4x + 3 8. (6x + 3) + (-5x + 8) = x + 11 9. (2 + 3y) + (5 + 8y) = 7 + 11y 10. (a^2b - ba^2 + 4) + (3a^2b - 40 + ba^2) - (7ab^2 - 3) = 4a^2b - 35 - 7ab^2 + 7
