32 1/7 + (129 - х/7) = 64 2/7
129 - х/7 = 64 2/7 - 31 1/7
129 - х/7 = 33 1/7
х/7 = 129 - 33 1/7
129 = 903/7
33 1/7 = 232/7
903/7 - 232/7 = 671/7
32 1/7 + (129 - 671/7) = 64 2/7
64 2/7 = 64 2/7
129 - х/7 = 64 2/7 - 31 1/7
129 - х/7 = 33 1/7
х/7 = 129 - 33 1/7
129 = 903/7
33 1/7 = 232/7
903/7 - 232/7 = 671/7
32 1/7 + (129 - 671/7) = 64 2/7
64 2/7 = 64 2/7

129 — х/7 = 64,2/7 — 32,1/7
129 — х/7 = 32,1/7
х/7 = 129 + 32,1/7
х/7 = 161,1/7
x = 161,1
129 — х/7 = 32,1/7
х/7 = 129 + 32,1/7
х/7 = 161,1/7
x = 161,1
