решите уравнение с дробями (7 класс)
1) х/4+х/3=7
2) 2х/5+х/2=9
3) 5х/4-х/2=3
4) 4х/5-х/10=7
5) 3х/4+5х/6=38

1 x/4+x/3 = 73x/12 + 4x/12 = 77x/12 = 7x/12 = 1x = 122 2x/5 + x/2 = 94x/10 + 5x/10 = 99x/10 = 9x/10 = 1x = 103 5x/4 - x/2 = 35x/4 - 2x/4 = 33x/4 = 3X/4 = 1X = 44 4x/5 - x/10 = 78x/10 - x/10 = 77x/10 = 7X/10 = 1X = 105 3x/4 + 5x/6 = 389x/12 + 10x/12 = 3819x/12 = 38X/12 = 2X= 12×2X=24
