Answer 1

5 6/7 - х = 3 2/7
41/7 - х = 23/7
х = 41/7 - 23/7 = 18/7 = 2 4/7

(у - 8 12/19) + 1 7/19 = 6 2/19
(у - 164/19) + 26/19 = 116/19
у - 164/19 = 116/19 - 26/19 = 90/19
у = 90/19 + 164/19 = 254/19 = 13 7/19

8 25/27 - (3 8/27 + 2 3/27) = 241/27 - (89/27 + 57/27) = 241/27 - 146/27 =
= 95/27 = 3 14/27

(8 3/17 - 7 15/17) + 3 4/17 = (139/17 - 134/17) + 55/17 = 5/17 + 55/17 =
= 60/17 = 3 9/17

х/8 = 4 3/8
х/8 = 35/8
х = 35/8 * 8 = 35
