Question

2/3-1/6x=7/12x+5/9 хелп​

Answer 1

2/3 - 1/6х = 7/12х + 5/9

2/3 - 5/9 = 7/12х + 1/6х

6/9 - 5/9 = 7/12х + 2/12х

9/12х = 1/9

х = 1/9 : 9/12

х = 1/9 · 12/9

х = (1·4)/(3·9)

х = 4/27

Проверка:

2/3 - 1/6 · 4/27 = 7/12 · 4/27 + 5/9

2/3 - 4/162 = 7/81 + 5/9

108/162 - 4/162 = 7/81 + 45/81

104/162 = 52/81 - верно
