Answer 1

Ответ:

x + 8 17/36) +7 31/36 = 25 1/36
(x + 8 17/36) = 25 1/36 - 7 31/36
(x + 8 17/36) = 24 37/36 - 7 31/36
(x + 8 17/36) = 17 6/36
x = 17 6/36 - 8 17/36
x = 16 42/36 - 8 17/36
x = 8 25/36


12 13/45 - ( y - 5 17/45) = 3 23/45
(y-5 17/45) = 12 13/45 - 3 23/45
(y-5 17/45) = 11 58/45 - 3 23/45
(y-5 17/45) = 8 35/45
y = 8 35/45 + 5 17/45
y = 13 52/45
