1) 4x=24+x 2) 8x-8=20-6x

1)
4x=24+x
4x-x=24
3x=24
x=24/3
x=8

2)
8x-8=20-6x
8x+6x=20+8
14x=28
x=28/14
x=2
  

1)
4х = 24 + х
4х - х = 24
3х = 24
х = 24 : 3
х = 8
----------------------
4 * 8 = 24 + 8
   32 = 32

2) 8х - 8 = 20 - 6х
8х + 6х = 20 + 8
14х = 28
х = 28 : 14
х = 2
----------------------------
8 * 2 - 8 = 20 - 6 * 2
   16 - 8 = 20 - 12
           8 = 8
