Пошаговое объяснение:

Answer 2

1. 2х • 3y = 6xy
2. 4 • 5 • 8v = 160v
3. 6(7 + x) = 42 + 6x
4. 2c + 6c - 5c = 3c
5. 5f + 7b - 2f + 6b = 3f + 13b
6. 9x - x - x = 7x
7. 34x + 12y + 9 - 4x + 65y + 15 = 30x + 77y + 24
8. 2(2x + 4y - 6a + 8) = 4x + 8y - 12a + 16
9. 6(16x + 4s) + 10(4x - 2s) = 96x + 24s + 40x - 20s = 136x + 4s
10. 56x(2x + 3y) = 112x^2 + 168xy
11. 12(3a + 5b + 7) + 5(4a - 2b + 9) = 36a + 60b + 84 + 20a - 10b + 45 = 56a + 50b + 129
12. 3ab + 4ab + 76 = 7ab + 76
13. x • y • 7 • f • 18 = 126xyf
14. (9v + 3p - 8k) • 7 = 63v + 21p - 56k
15. a + a = 2a
16. b + b + b - 3b = b
17. (4x + 6y) • 5 + (5x - 2y) • 10 = 20x + 30y + 50x - 20y = 70x + 10y
18. 23(3x + 4) + 56 = 69x + 92 + 56 = 69x + 148
19. 6f + 10b - (5f + 2b) = 6f + 10b - 5f - 2b = f + 8b
20. (6a + 3b) - 2a = 4a + 3b
21. 6x - (2y - 4x) = 6x - 2y + 4x = 10x - 2y
22. 65x • 2 • 4 = 520x
23. 34 - (2x - 5) = 34 - 2x + 5 = 39 - 2x
24. 58 - (53d + 12) = 58 - 53d - 12 = 46 - 53d
25. -2(3x + 4y - 5a) - 6(-2x - 6y + 9a) = -6x - 8y + 10a + 12x + 36y - 54a = 6x + 28y - 44a
26. -(5a - 6d + 7c) - 7(3a + 5d - 11c) = -5a + 6d - 7c - 21a - 35d + 77c = -26a - 29d + 70c
