решите уравнение 1 19/27: (x-1 5/18) * 1 7/38=15/19

1 19/27 : (x - 1 5/18) * 1 7/38 = 15/19.

(1 * 27 + 19) / 27 : (х - (1 * 18 + 5) / 18) = 15/19 : (1 * 38 + 7) / 38,

46/27 : (х - 23/18) = 15/19 : 45/38,

46/27 : (х - 23/18) = 15/19 * 38/45,

46/27 : (х - 23/18) = 2/3,

х - 23/18 = 46/27 : 2/3,

х - 23/18 = 46/27 * 3/2,

х - 23/18 = 23/9,

х = 23/9 + 23/18,

х = (23 * 2) / 18 + 23/18,

х = 46/18 + 23/18,

х = (46 + 23) / 18,

х = 69/18,

х = 3 15/18,

Ответ: х = 3 15/18.
