1) x – 4 5/11 = 5 6/11
x = 5 6/11 + 4 5/11
x = 10
10 – 4 5/11 = 5 6/11
5 6/11 = 5 6/11
2) 7 18/49 – x = 2 18/49
х = 7 18/49 – 2 18/49
х = 5
7 18/49 – 5 = 2 18/49
2 19/49 = 2 18/49
3) x + 2 8/13 = 11
x = 11 – 2 8/13
x = 8 5/13
8 3/13 + 2 8/13 = 11
11 = 11
4) x – 7/11 = 8 4/11
x = 8 4/11 + 7/11
x = 9
9 – 7/11 = 8 4/11
8 4/11 = 8 4/11
