1. 4(a + b + c) = 4a + 4b + 4c
2. (a + b + c) \cdot 5 = 5a + 5b + 5c
3. -7 \cdot (x + y + z) = -7x - 7y - 7z
4. -5(a - b - c) = -5a + 5b + 5c
5. 2(3x - 4y + 5z) = 6x - 8y + 10z
6. -4 \cdot (-2x + 6y - 3k + m) = 8x - 24y + 12k - 4m
7. 10(4x - 5y) = 40x - 50y
8. (6a + 3b - d) \cdot (-3) = -18a - 9b + 3d
9. -(a + b + c) = -a - b - c
10. (x + y + z) - 2(m + n + p) = x + y + z - 2m - 2n - 2p
11. 4(3a + 2) - (b - 5c) = 12a + 8 - b + 5c
12. 6(3m + n - 7k) = 18m + 6n - 42k

Ответ:

• 4(a + b + c) = 4a + 4b + 4c
• (a + b + c) ⋅ 5 = 5a + 5b + 5c
• -7 ⋅ (x + y + z) = -7x - 7y - 7z
• -5(a - b - c) = -5a + 5b + 5c
• 2(3x - 4y + 5z) = 6x - 8y + 10z
• -4 ⋅ (-2x + 6y - 3k + m) = 8x - 24y + 12k - 4m
• 10(4x - 5y) = 40x - 50y
• (6a + 3b - d) ⋅ (-3) = -18a - 9b + 3d
• -(a + b + c) = -a - b - c
• (x + y + z) - 2(m + n + p) = x + y + z - 2m - 2n - 2p
• 4(3a + 2) - (b - 5c) = 12a + 8 - b + 5c
• 6(3m + n - 7k) = 18m + 6n - 42k
