  01 -

  9 + 2(5x-4) = 2

  9 + 10x - 8 = 2

  10x + 1 = 2

  10x = 1

  x = 1 / 10

  x = 0,1

  9+2(5x - 4) = 2

  9 + 10x - 8 = 2

  10x = 2 - 9 + 8

  10x = 1

  x = 1/10 ou 0,1 na forma decimal

  Multiplique o 2 por 5X e pelo -4

  9+10x-8=2

  Diminua 9 - 8 = 1

  1+10x=2

  Iguale 10x

  10x = 2-1

  10x = 1

  x= 1/10 ou 0,1
