Уравнения: 2 1/3 + x = 3 1/6 4 * x = 12 4/5 х : 5/6=2 2/5 5 2/9 * x= 0 заранее спасибо
2 1/3 + x = 3 1/6 7/3 + х = 19/6 х = 19/6 - 7/3 х = 19/6 - 14/6 х = 5/6 4 * x = 12 4/5 4х = 64/5 х = 64/5 : 4 х = 64/5 * 1/4 х = 16/5 х = 3,2 х : 5/6=2 2/5 х : 5/6 = 12/5 х = 12/5 * 5/6 х = 2 5 2/9 * x= 0 х = 0 * 5 2/9 х = 0
