Решите уравнение 1целая1/3+1целая5/6=2целых2/3-2целых1/6X
1) 1 1/3+1 5/6=2 2/3-2 1/6х 2 1/6х=2 2/3-1 1/3- 1 5/6 13/6х=8/3-4/3-11/6 13/6х=16/6-8/6-11/6 13/6х= -3/6 х =-3/6:13/6 х=-3/6*6/13 х=-3/13.
1 1/3 + 1 5/6 = 2 2/3 - 2 1/6х 4/3 + 11/6 = 8/3 - 13/6х 8/3 - 13/6х = (8+11)/6 = 19/6 13/6х = 8/3 - 19/6 = (16-19)/6 = -3/6 х = -3/6 : 13/6 = -3/6 * 6/13 = -3/13
