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
