Question

SVP Pour Demain !!
A= 11 + 2 ( x - 6 ) + 4 ( - 3x - 6 )
B = - 2 ( x - 5 ) - 3 ( 7 - 4 x )

2 Réponse

  • A= 11 + 2x-12 -12x-24
    A= -25-10x

    B= -2x+10 -(21+12x)
    B= -2x+10 - 21-12x
    B= -14x-11
  • A= 11 + 2 ( x - 6 ) + 4 ( - 3x - 6 )
    = 11 + 2 * x + 2 * (-6) + 4 * (-3x) + 4 * (-6)
    = 11 + 2x - 12 - 12x - 24
    = -1 - 10x - 24
    = -10x - 25

    B = - 2 ( x - 5 ) - 3 ( 7 - 4 x )
    = -2 * x - 2 * (-5) - 3 * 7 - 3 * 4x
    = -2x + 10 - 21 - 12x
    = -14x - 11
