bonjour

A = 8 x +18 x + 2 = 26 x +2

B = 9 x + 5 - 2 x +3 = 7 x + 8

C = 4 x - 9 - 2 x - 7 = 2 x - 16

D = 9 x + 5  -2 x + 3 = 7 x + 8

e = 4 x - 9 - 2 x + 7 = 2 x - 2

F = 8 x + 3 - 6 x - 2 = 2 x + 1

Bonjour,

A= 8x + 3 ( 6x + 2 )=

8x +18x +6 =

26x +6

B= ( 9x + 5 ) + ( - 2x + 3 )=

9x +5 -2x -3 =

7x +2

C= ( 4x - 9 ) - 2x - 7=

4x-9 -2x -7=

2x -16

D= ( 9x + 5 ) - 2x + 3=

9x+5 -2x +3 =

7x +8

E= ( 4x - 9 ) - 2x + 7=

4x-9 -2x +7=

2x -2
