Question

1. 2x - 5x + 9x=2x-5x+9x=-3x+9x=6x

2. 2x + 7x + x – 8x =2x+7x+-8x=10x-8x=2x

3. 5xy – 3x + 4xy =(5xy+4xy)-3x=9xy-3x

4. 6x – 8y – 4y=6x-8y-4y=6x+(-8-4)y=6x-12y

5. 3y + 5y – 7y + x=3y+5y-7y+x=y+x

6. 8z + 3xy – 12z=8z-12z+3xy-4z+3xy

7. 5m – 9n + 2n=5m-9n+=5m-7n-9ny2n

8. 10x + 4y – y=10x+4y-y -y-4y 10x.=5y 10. 10 x=50y

9. 6z – 4z + 2z=6z-4z+2z=42

10. 3x – 7y + 5x + 4y=8x-3y

11. 6b – 3b + 8a – 18b + a=6b-3b+8a-18b+9 6b-3b-18b+8a-15b+9a

12. 9z + 8zy² – 5z + zy² – 15xy²=4z+9y²z-15xy²

13. x + 3xy – 6x – 2x + 8xy + y – 2xy=9xy-7x+y

14. 8n – 4mn + 4n – 3mn + 5m=12n-7mn+5m

15. 24m²n – 2mn – 12m²n – m³=12n-7mn+5m
3y+5y-7y+x=y+x
