решите уровнения 1) 14 - 1/2x = 0 2) 4x+ 5 = 4(x-2) + 4x 3) 4 - 2x/3 + x/6 = 0

1) 14 = 0.5x
     x = 14/0.5 = 28
2) 4x + 5 = 4x - 8 + 4x
    8x - 4x = 5 + 8
    4x = 13
      x = 13/4 
3) 4 - 2x/3 + x/6 = 0
    x/6 - 2x/3 = -4
    x/6 - 4x/6 = -4
    -3x/6 = -4
    -x/2 = -4
    -x = -8
     x = 8
