Odpowiedź :

Odpowiedź:

1.

6x + 3x - 5 = 9x-5

2.

4a - 6 + 7a = 11a - 6

3.

5m + 8 - m = 4m +8

4.

2p - 4 -5 -9p = -7p -9

5.

-5a + 3b + 8b - a = -6a +11b

6.

28 - 14y

7.

-12x -6

Odpowiedź:

6x + (3x-5)= 6x +3x -5= 9x +5

4a - ( 6-7a) = 4a -6 + 7a = 11a -6

( 5m+8) -m= 5m +8 -m= 4m+8

( 2p-4 ) - ( 5+9p)= 2p-4 -5 -9p = -7p -9

- ( 5a-3b) + ( 8b-a)= -5a +3b + 8b -a= -6a + 11b

7 ( 4-2y)= 28 - 14y

  -6 ( x+1)= -12x -6
