5x + 3= 0
2x - 4 = 0
-6x +3 =0
-5x + 7=0

2 Réponse

  • 5x = -3
    x = -3/5
    x= -0,6

    2x = 4
    x = 2/4
    x = 0,5

    -6x = -3
    x = -3/-6
    x= 0,5

    -5x = -7
    x = -7/-5
    x = 1,4
  • 5x + 3= 0
    5x = -3
    x = -3/5

    2x - 4 = 0
    2x = 4
    x= 4/2
    x =2

    -6x +3 =0
    -6x = -3
    x = -3/-6
    x = 1/2

    -5x + 7=0

    -5x = -7
    x= -7/-5
    x = 7/5
