Пошаговое объяснение:

11. 2/3х - 5. 1/6 = 3. 3/4 + 2. 3/4х

11. 2/3х - 2. 3/4х = 3. 3/4 + 5. 1/6

11. 8/12х - 2. 9/12х = 3. 9/12 + 5. 2/12

10. 20/12х - 2. 9/12х = 8. 11/12

8. 11/12х = 8. 11/12

х = 8. 11/12 : 8. 11/12

х = 1

11 2/3х - 5 1/6 = 3 3/4 + 2 3/4х

11 2/3х - 2 3/4х = 3 3/4 + 5 1/6

35/3х - 11/4х = 15/4 + 31/6

150/12х - 33/12х = 45/12 + 62/12

117/12х = 107/12 х

х = 117/12 : 107/12

х = 117/107

ответ: х = 117/107 = 1 10/107
