Answer 1

-a+2a-8a+2=-7а+2
12-3n+5n=3n+12
6x-12-7x=-12-x
-6a-12a-7=-18a-7
9d-3d-20=6d-20
-8a+6a-5a=-7a
x-6-3x+9=-2x+3
-5-(8-m)=-5-8+m=-13+m
-2x+(4+m)-5x=-2x+4+m-5x=-7x+m+4
2-(4+m)-5=2-4-m-5=-m-7
4m-(4+m)+5=4m-4-m+5=3m+1
2m+(4-m)+5=2m+4-m+5=m+9
15-(8+m)=15-8-m=7-m
-x+5y+6x+5y=5x+10y
-5(x+2)+2(x-3)=-5x-10+2x-6=-3x-16
14*(3x+5y)=42x+70y
(2x-19)-5x+5=2x-19-5x+5=-3x-14
8-(3x+y+7)=8-3x-y-7=1-3x-y
2(5a+2)-3*(a+3)=10a+4-3a-9=7a-5
5(4x+3y)-7(2x-y)=20x+15y-14x+7y=6x+22y
2*(a+2b+3c)-4(a-b)=2a+4b+6c-4a+4b=-2a+8b+6c

Answer 2

Let's simplify each expression step by step:

1. -a + 2a - 8a + 2 Combine like terms: = (-1 + 2 - 8)a + 2 = -7a + 2

2. 12 - 3n + 5n Combine like terms: = (12) + (5n - 3n) = 12 + 2n

3. 6x - 12 - 7x Combine like terms: = (6x - 7x) - 12 = -x - 12

4. -6a - 12a - 7 Combine like terms: = (-6 - 12)a - 7 = -18a - 7

5. 9d - 3d - 20 Combine like terms: = (9d - 3d) - 20 = 6d - 20

6. -8a + 6a - 5a Combine like terms: = (-8 + 6 - 5)a = -7a

7. x - 6 - 3x + 9 Combine like terms: = (x - 3x) + (9 - 6) = -2x + 3

8. -5 - (8 - m) Distribute the negative sign inside the parentheses: = -5 - 8 + m = -13 + m

9. -2x + (4 + m) - 5x Combine like terms: = (-2x - 5x) + (4 + m) = -7x + 4 + m

10. 2 - (4 + m) - 5 Distribute the negative sign inside the parentheses: = 2 - 4 - m - 5 = -m - 7

11. 4m - (4 + m) + 5 Distribute the negative sign inside the parentheses: = 4m - 4 - m + 5 Combine like terms: = 3m + 1

12. 2m + (4 - m) + 5 Distribute the positive sign inside the parentheses: = 2m + 4 - m + 5 Combine like terms: = m + 9

13. 15 - (8 + m) Distribute the negative sign inside the parentheses: = 15 - 8 - m Combine like terms: = 7 - m

14. -x + 5y + 6x + 5y Combine like terms: = (-x + 6x) + (5y + 5y) = 5x + 10y

15. -5(x + 2) + 2(x - 3) Distribute the negative sign and positive sign inside the parentheses: = -5x - 10 + 2x - 6 Combine like terms: = -3x - 16

16. 14*(3x + 5y) Distribute the 14 inside the parentheses: = 14 * 3x + 14 * 5y = 42x + 70y

17. (2x - 19) - 5x + 5 Combine like terms: = 2x - 5x - 19 + 5 = -3x - 14

18. 8 - (3x + y + 7) Distribute the negative sign inside the parentheses: = 8 - 3x - y - 7 Combine like terms: = -3x - y + 1

19. 2(5a + 2) - 3(a + 3) Distribute the 2 and -3 inside the parentheses: = 2 * 5a + 2 * 2 - 3 * a - 3 * 3 = 10a + 4 - 3a - 9 Combine like terms: = 7a - 5

20. 5(4x + 3y) - 7(2x - y) Distribute the 5 and -7 inside the parentheses: = 5 * 4x + 5 * 3y - 7 * 2x - 7 * (-y) = 20x + 15y - 14x + 7y Combine like terms: = 6x + 22y

21. 2 * (a + 2b + 3c) - 4(a - b) Distribute the 2 and -4 inside the parentheses: = 2 * a + 2 * 2b + 2 * 3c - 4 * a + 4 * b = 2a + 4b + 6c - 4a + 4b Combine like terms: = -2a + 8b + 6c
