Пошаговое объяснение:
1) 17 1/4 - x = 7 11/12;
-x=7 11/12 - 17 1/4;
-x= -(17 1/4 - 7 11/12);
x=17 3/12 - 7 11/12;
x= 16 (12+3)/12 - 7 11/12;
x=9 4/12;
x=9 1/3.
---------------
2) (x - 7 1/6) + 4 7/18 = 5 1/9;
x-7 1/6 = 5 1/9 - 4 7/18;
x-7 1/6= 5 2/18 - 4 7/18;
x- 7 1/6 = 4 20/18-4 7/18;
x-7 1/6 = 13/18;
x=13/18+7 1/6;
x=13/18 + 7 3/18;
x=7 16/18;
x=7 8/9.
