Решите уравнение (1,7: (х-10,25)) * 21 1/4=2 5/6

(1,7 : (Х - 10,25)) • 21 1/4 = 2 5/6

1,7 : (Х - 10,25) = 2 5/6 : 21 1/4

2 5/6 : 21 1/4 = 17/6 : 85/4 = 34/255

1,7 : (Х - 10,25) = 24/255

Х - 10,25 = 1,7 : (24/255)

1,7 : (24/255) = 17/10 : (24/255) = 289/16 = 18,0625

Х - 10,25 = 18,0625

Х = 18,0625 + 10,25

Х = 28,3125
