salut !

8x + 10x +4+9=18x+13

b.y + 9 + 3y + 4=4y+13

d. -5 – 4w – 8w + 10 =-12w-5

c. 112 + 12 + 5z – 5 =124-5+5z=119+5z

e.  - 4m - 6 + 8m + 1 =-4m-5

f. -3x + 5 – 7x + 2x – 6x – 6 = -16x+2x-1=-14x-1

g. 4x – 5 + 6x2 + 4 – 2x2 - x +x2 – 7x = 4x-5+12+4-4-x+2x-7x=-2x+7

Voilà j'espère t'avoir aidé

8x + 10x +4+9

=18X+ 4+9

=18X+13

y + 9 + 3y + 4

=4Y +9+4

=4Y+13

112 + 12 + 5z – 5

=124+5Z-5

=119+5Z

-5 – 4w – 8w + 10

=-5-12W+10

=5-12W

- 4m - 6 + 8m + 1

=4M-6+1

=4M-5

-3x + 5 – 7x + 2x – 6x – 6

=-3X-1-7X+2X-6X

=-10X-1+2X-6X

=-8X-6X-1

=-14X-1

4x – 5 + 6x2 + 4 – 2x2 - x +x2 – 7x

=4X-5+12+4-4-X+2X-7X

=4X+7+4-4-X+2X-7

=4X+11-4-X+2X-7

=4X+7-X-2X-7

=4X+0-X-2X

=3X-2X

=X+0(X)
