Question

-3(2+x)-5x=6-2(-8+x) 8x-2=3-5x 1.7x-8 =x

Answer 1

- 3(2 + х) - 5х = 6 - 2(- 8 + х)
- 6 - 3х - 5х = 6 + 16 - 2х
- 3х - 5х + 2х = 22 + 6
- 6х = 28
х = 28 : (-6) = - 28/6
х = - 4 2/3

8х - 2 = 3 - 5х
8х + 5х = 3 + 2
13х = 5
х = 5/13

1,7х - 8 = х
1,7х - х = 8
0,7х = 8
х = 8 : 0,7 = 80 : 7
х = 11 3/7
