Answer 1

Ответ:

3b + (5 - 7b) = -4b + 5

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

3(8a - 4) + 6a = 30a - 12

7p - 2(3p - 1) = p + 2

-2(x + 4) + 10(x - 2) = 8x - 22

-2(x - 2y) + 3(x - 5y) = x - 16y

-(a + b - m - n) + 2(m + n - a - b) = 2(m + n) - 2(a + b)

2(3x - 6y - 9) - 3(2x - 4y - 6) = -x - 12y - 15

2(x + 7y - 5) - 3(x + y) = -x + 13y - 10

-4(2x - 7y + 8a) + 13x - 3(y - 7a) = 5x - 49y + 29a

-0,2(4b - 7) + 1,4b = 1,02b - 1,4

3a(7 - b) - 7(b - 3a) = -4ab + 28a + 7b

(3x - 11) × 0,2 - 5(0,4 - 0,3x) = -0,9x - 0,2

-3,5(3a - 2b) + 2(1,3a - b) = -9,9a + 8,5b

0,5(1,6x - 6,4y) - 2,4(1,5x + y) = -2,8x - 2,6y
