Пошаговое объяснение:

4 1/6 : (1/2x + 1 4/17 ) - 1 5/6 = 7/9

4 1/6 : (1/2x + 1 4/17 )  = 7/9 + 1 5/6

4 1/6 : (1/2x + 1 4/17 ) = 14/18 + 1 15/18

4 1/6 : (1/2x + 1 4/17 ) = 1 29/18

1/2x + 1 4/17 = 4 1/6 : 1 29/18

1/2x + 1 4/17  = 25/6 * 18/47

1/2x + 1 4/17 = 75/47

1/2x = 75/47 - 1 4/17

1/2x = 75/47 - 21/17

1/2x = 1275/799 - 987/799

1/2x = 288/799

x = 288/799 * 2

x = 576/799
