4. Реши уравнение
(14/39 - y) + 10/39 = 23/39
t/118 + 2 112/118 = 5 11/118
18/15+ x = 5 11/18
Ответ
3
(14/39 - у) + 10/39 = 23/39
14/39 - у + 10/39 = 23/39
8/13 - у = 23/39
-у = 23/39 - 8/13
-у = -1/39
у= 1/39
t/118 + 2 112/118 = 5 11/118
t/118 + 348/118 = 601/118
t + 348 = 601
t = 601 - 348
t = 253
18/15+ x = 5 11/18
6/5 + x = 101/18
x = 101/18 - 6/5
x = 397/90
x = 4 37/90
14/39 - у + 10/39 = 23/39
8/13 - у = 23/39
-у = 23/39 - 8/13
-у = -1/39
у= 1/39
t/118 + 2 112/118 = 5 11/118
t/118 + 348/118 = 601/118
t + 348 = 601
t = 601 - 348
t = 253
18/15+ x = 5 11/18
6/5 + x = 101/18
x = 101/18 - 6/5
x = 397/90
x = 4 37/90
