Answer 1

Пошаговое объяснение:

3. 1/9(1. 5/28х - 0,3) = 1,5 - 5/6(7 - х)

28/9(33/28х - 3/10) = 15/10 - 5/6(7 - х)

28/9*33/28х - 28/9*3/10 = 15/10 - 5/6*7 + 5/6*х

1/3*11/1х - 14/3*1/5 = 3/2 - 35/6 + 5/6х

11/3х - 14/15 = 1. 1/2 - 5. 5/6 + 5/6х

11/3х - 14/15 = 1. 3/6 - 5. 5/6 + 5/6х

11/3х - 14/15 = -4 2/6 + 5/6х

11/3х - 14/15 = -4. 1/3 + 5/6х

11/3х - 5/6х = -4. 1/3 + 14/15

22/6х - 5/6х = -4. 5/15 + 14/15

17/6х = -3. 20/15 + 14/15

17/6х = -3. 6/15

17/6х = -3. 2/5

17/6х = -17/5

х = -17/5 : 17/6

х = -17/5 * 6/17

х = -1/5 * 6/1

х = -6/5

х = -1,2 или -1. 1/5
