А)1-1 1/2+3 2/5a=1 1/3а-2 7/15а+2 1/2
1/2+3 2/5х=1 5/15а-2 7/15а+2 1/2
1/2+3 2/5х=17/15а+2 1/2
3 2/5а-17/15а=2 1/2-1/2
51/15а-17/15а=2
34а=2
а=2÷34
а=1/17
б) x-1.2/ 3.2 = x- 3.45 / 1.7
Избавится от знаменателя
(х-1,2)*1,7=(х-3,45)*3,2
1,7х-2,04=3,2х-11,04
1,7х-3,2х=2,04-11,04
- 1,5х= - 9,0
1,5х=9,0
х=9,0÷1,5
