Penjelasan dengan langkah-langkah:

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

= (5 - 3)x + (2 + 1)y

= 2x + 3y

2. -7a + 2b + 6b - 2a

= (-7 - 2)a + (2 + 6)b

= -9a + 8b

3. a - 4b + 7 - 3a + 8b

= (1 - 3)a - 4b + 8b

= -2a + 4b

4. 4x² + 3x²

= (4 + 3)x²

= 7x²

5. x² + 9x - 8x² - x

= (1 - 8)x² + (9 - 1)x

= -7x² + 8x

6. -3x² - 7x + 3x² +2x

= (-3 + 3)x² - 7x + 2x

= -5x

7. 2x² - 6x - 2 -3x

= 2x² + (-6 - 3)x - 2

= 2x² - 9x - 2

8. x² - 8x + 4 - 3x² + 8x

= (1 - 3)x² + (-8 + 8)x + 4

= -2x² + 4
