10 3/13
Пошаговое объяснение:
(x - 3 9/13) + 5 10/13 = 12 4/13
х - 3 9/13 = 12 4/13 - 5 10/13
х - 3 9/13 = 11 17/13 - 5 10/13
х - 3 9/13 = 6 7/13
х = 6 7/13 + 3 9/13
х = 9 16/13
х = 10 3/13
х=10 3/13
(x-3 9/13)+5 10/13=12 4/13
x-3 9/13=12 4/13 -5 10/13
x-3 9/13=12 4/13 -5 10/13+3 9/13
х=10 4/13-10/13+9/13= 10 13/13-10/13=10 3/13
