Ответы

Автор ответа: GlebGor1998

3 1/8 / (х - 4 7/24) = 17/18 + 1 5/6
25/8 / (х - 4 7/24) = 17/18 + 1 15/18
25/8 / (х - 103/24) = 2 14/18
25/8 / (х - 103/24) = 50/18
25/8 = (х -103/24) * 50/18
25/8 = 50/18 *х - 2575/216 , умножим левую и правую часть уравнения на 216
Получим : 675 = 600х - 2575
600х = 675 + 2575
600х = 3250
х = 3250/600
х = 5 5/12
