2. 9a - 6a =
3. -7b + b =
4. -y - 4y =
5. 0,4x + 0,6x =
6. 4/5a - 1/5a =
tolong di jawab ya ka pakai cara nya ​

Penjelasan dengan langkah-langkah:

1. 5x + 2x

=> 5 + 2x = 7x

2. 9a - 6a

=> 9 - 6a = 3a

3. -7b + b

=> -7 - 1b = -6b

4. -y - 4y

=> -1 - 4y = -5y

5. 0,4x + 0,6x

=> 0,4 + 0,6x = 1x

6. 4/5a - 1/5a

=> (0,8) - (0,2) = 0,6a
