1. у = 6 13/21
2. х = 3 6/25
3. у = 13/14
Пошаговое объяснение:
1. (у + 5/7) * 1/3 = 2 4/9
1/3у + 5/7 * 1/3 = 22/9
1/3у + 5/21 = 22/9
1/3у = 22/9 - 5/21
1/3у = (22*7 - 5*3) /63
1/3у = 139/63
у = 139/63 : 1/3 = 139/63 * 3
у = 139/21 = 6 13/21
2. (1 16/25 + x) - 4/5 = 4 2/25
(41/25 + х) - 4/5 = 102/25
41/25 + х - 4/5 = 102/25
х = 102/25 - 41/25 + 4/5
х = 61/25 + 4/5
х = 81/25 = 3 6/25
3. (8 3/14 - y) : 3/7 = 17
(115/14 - y) : 3/7 = 17
115/14 - y = 17 * 3/7
115/14 - y = 51/7
-у = 51/7 - 115/14
-у = -13/14
у = 13/14
