Решите уравнение:а)1 3/7-3/14x=5/7
б)-1 7/12-1 3/4x=1/8

1 ( 3/7 ) - ( 3/14 ) X = 5/7 ( 10/7 ) - ( 3/14 ) X = 5/7 ( 20 - 3X ) / 14 = 10/14 20 - 3X = 10 3X = 20 - 10 3X = 10 X = 3 ( 1/3 ) --------------------------------- 1 ( 7/12 ) - 1 ( 3/4 ) X = 1/8 - ( 19/12 ) - ( 7/4 ) X = 1/8 ( 76 - 84X ) / 48 = 6/48 76 - 84X = 6 84X = 70 X = 70/84 = 35/42 = 5/6
