Ответ:
1. х = 2/5
2. х = 2
3. х = 2 9/15
Пошаговое объяснение:
1) x + 4/5 = 1 1/5
х + 4/5 = 6/5
х = 6/5 - 4/5
х = 2/5
2) x + 11/13 = 2 11/13
х + 11/13 = 37/13
х = 37/13 - 11/13
х = 26/13
х = 2
3) x - 13/15 = 1 11/15
х - 13/15 = 26/15
х = 26/15 + 13/15
х = 39/15
х = 2 9/15
1) 1.4
2) 2
3) 2.6
1) х=11/5-4/5
х=7/5
х=1.4
2) х=2 11/13 - 11/13
х=37/13 - 11/13
х=26/13
х=2
3) х=1 11/15 + 13/15
х=26/15 + 13/15
х=39/15
х=2.6
