1. -7+6+8z-4= -5 + 8z
2. -8x² -1-4x² + x²= - 13x² - 1
3. -5-5+3b-6= -16 +3b
4. -7z²+b-9b-2z² + 7= -9z² - 8b + 7
5. 3xy - 4 + 6xy + 5x-6= 9xy - 10 + 5x
6. -8ay + 7cx + 5 + 3cy + 8ay =7zx + + 5 + 3cy
7. -7+8by-7ay+6+by = - 1 +9ab - 7ay
8. -5ac + 8 -2by +7az - 3by = -5ac + 8 - 5by + 7az
9. -8c - 9y +6c +4 + 9y = -2c + 4
10. a - 5y² - 3y² - 8-6a = -5a - 8y² - 8

O to chodzi?
