Penjelasan dengan langkah-langkah:
1a. 12m + 3 + n + 3n + 2m = (12 + 2)m + (1 + 3)n + 3 = 14m + 4n + 3
b. 7a + 5b + 2a + 10 = (7 + 2)a + 5b + 10 = 9a + 5b + 10
c. 5x – 3y – 6 – 2 – 4y = 5x – (3 + 4)y – (6 + 2)
= 5x – 7y – 8
2. 2x (6x + 3 – 4x) = 2x (2x + 3) = 4x² + 6x
3. (12xy + 8xy²) : 4y = 4y (3x + 2xy) : 4y = 3x + 2xy.
