Пошаговое объяснение:
1) x-2 7/12= 5 3/18
x=2 7/12+ 5 3/18
x=2 21/36+ 5 6/36
x=7 27/36
x=7 3/4
2) x-26 7/21= 100 5/28
x= 26 7/21+ 100 5/28
x= 26 28/84+ 100 15/84
x= 126 43/84
3) x- 37 17/54= 15 16/45
x= 37 17/54+ 15 16/45
x= 37 85/270+ 15 96/270
x= 52 181/270
4) x- 33 21/25= 42 17/35
x= 33 21/25+ 42 17/35
x= 33 147/175+ 42 85/175
