bonjour aidez moi svp

Bonjour,

4(6x-4) = 24x-16

-6(4x+4) = -24x-24

-4(6x-4) = -24x+16

2(6x+7) = 12x+14

6(4x+4) = 24x+24

4(6x+4) = 24x+16

-4(6x+4) = -24x-16

-6(4x-4) = -24x+24

5x²-8x² = -3x²

-5x-8x = -13x

-5x²+8x² = 3x²

5x-8x = -3x

-5x²-8x² = -13x²

-5x+8x = 3x

5x+8x = 13x

5x × 8x = 40x²

5x²+8x² = 13x²

Bonne journée
