1. 2a + a =

Jawaban:

semoga membantu

Penjelasan dengan langkah-langkah:

1. 2a + a =3a

2. 5b + 3b + b =9b

3. 2x + 4x + 3x – 7x =9x-7x=2x

4. 3y – 7y = -4y

5. 3p + 2p – 8p = -3p

6. 3a + 2b + 5a + 7b =3a+5a+2b+7b=8a+9b

7. 2x + 5y + 3a – 4y =2x+y+3a

8. 4m + 5n – 3m – 4n =m-n

9. 2a + 3b + 4c + 6a + 7b + 8c =2a+6a+3b+7b+4c+8c

=8a+10b+12c

10. 5x + 6y + 7z – 2x – y =5x-2x+6y-y+7z=3x+5y+7z

Jawaban:

1. 2a + a = 3a

2. 5b + 3b + b = 9b

3. 2x + 4x + 3x – 7x = 2x

4. 3y – 7y = -4y

5. 3p + 2p – 8p = -3p

6. 3a + 2b + 5a + 7b = 8a + 9b

7. 2x + 5y + 3a – 4y = 2x + 3a + y

8. 4m + 5n – 3m – 4n = m + n

9. 2a + 3b + 4c + 6a + 7b + 8c = 8a + 10b + 12c

10. 5x + 6y + 7z – 2x – y = 3x + 5y + 7z
