Решите уравнения 2(х-3)=3(4-х)+5 4/5х+6(3-2/5х)=17

2(х-3) = 3(4-х) + 5
2х - 6 = 12 - 3х + 5
2х - 6 = 17 - 3х
2х + 3х = 17 + 6
5х = 23 | ÷5
х = 23/5
х = 4.6

4/5х + 6(3-2/5х) = 17
4/5х + 6 × 15х - 2/5х = 17
4/5х + 6(15х - 2)/5х = 17
4/5х + 6(15х - 2)/5х = 17, х не равно 0
4/5х + 90х - 12/5х = 17
4 + 90х - 12/5х = 17
- 8 + 90х/5х = 17
- 8 + 90х = 85х
90х - 85х = 8
5х = 8
х = 8/5, х не равно 0
х = 1,6
