Answer 1

Ответ:

Объяснение:

12. 1) = 6x

2) = - 66y

3) = 2.8t - 5.3z

4) = 5.5a - 0.6

5) = 2.9x - 1.6d - 3.4c + 4.3

5) = -x/12 - 5y/36

13. 1) = 48x - 56 - 17x = 31x -56

2) = 9y - 85 + 5y = 14y - 85

3) = 2.4x - 1.8 + 2.1x - 10.5 = 4.5x - 12.3

4) = 10a - 20b - 4.2a + 5.6b = 5.8a - 14.4b

5) = 5.2 + 3.1t - 2.4t + 6.4 = 0.7t + 11.6

6) = 3x - 3y/8 - x + 2y = 2x + 1⁵/₈y
