Question

помогите ребята!!!!!!!!!!!!!! даю 25 баллов
1. ( 6x - 3 ) - ( 4 - 2x) =
2. 12+ ( x - 3 ) - ( - 3x + 12 ) =
3. ( 25 - 3x) + ( -2x + 6 )=
4. 2a + 3b + ( 4a - b ) =
5. ( - a + b ) - ( b + a ) =

Answer 1

1. ( 6x - 3 ) - ( 4 - 2x) = 6х - 3 - 4 + 2х = 8х - 7.
2. 12+ ( x - 3 ) - ( - 3x + 12 ) = 12 + х - 3+ 3х - 12 = 4х - 3.
3. ( 25 - 3x) + ( -2x + 6 ) = 25 - 3х - 2х + 6 = -5х + 31.
4. 2a + 3b + ( 4a - b ) = 2а + 3b + 4a - b = 6a + 2b.
5. ( - a + b ) - ( b + a ) = -а + b - b - a = -2a.
Удачи)))

Answer 2

-8c+4+4=-8c+8

Answer 3

-3n - (8m - 3n) = -3n - 8m + 3n = -8m.

Answer 4

Да да

Answer 5

-8с + 8) ошиблась

Answer 6

)))

Answer 7

1. =6x-3-4+2x
=8x-7

2. =12+x-3+3x-12
=4x-3

3. =25-3x-2x+6
= -5x+31

4. =2a+3b+4a-b
=6a+2b

5. = -a+b-b-a
= -2a
