Question

22•(17/26x-3/4)=5 1/13

Answer 1

374/26х-66/4=66/13 , тк 22/1*17/26х=374/26х
374/26х=66/13+66/4
374/26х=858/52+264/52
374/26х=1122/52
х=1122/52 делим на 374/26= 1122/52*26/374=3/2=1,5
проверяем:
22/1(17/26*3/2-3/4)=5 1/13 
22/1(51/52-3/4)=5  1/13
22/1(51/52-39/52)=22/1*12/52=264/52=5 1/13
