Penjelasan dengan langkah-langkah:

1.) 2x + 3y + 5x + 2y

= (2 + 5)x + (3 + 2)y

= 7x + 5y

2.) 4x + 9 + 5x + 2

= (4 + 5)x + (9 + 2)

= 9x + 11

3.) 2y + 3x + 2y + 3x

= (2 + 2)y + (3 + 3)x

= 4y + 6x

4.) 9a° + 3ab + 7b° + 12a° + 6ab + 2b°

= (9 + 12)a° + (3 + 6)ab + (7 + 2)b°

= 21a° + 9ab + 9b°
