Answer 1

Respuesta:

2x – 5x + 9x = 6x

2x + 7x + x – 8x = 2x

5xy – 3x + 4xy= 9xy - 3x

6x – 8y – 4y = 6x -12y

3y + 5y – 7y + x = y - x

8z + 3xy – 12z = -4z + 3xy

5m – 9n + 2n= 5m - 7n

10x + 4y – y= 10x + 3y

6z – 4z + 2z = 4z

3x – 7y + 5x + 4y = 8x  - 3y

6b – 3b + 8a – 18b + a = -15b + 9a

9z + 8zy 2 – 5z + zy 2 -15xy 2 =

4z+16zy+2zy-30xy

4z+18zy-30xy (se ordena y queda así):

-30xy+18yz+4z

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

8n – 4mn + 4n – 3mn + 5m = 12n -7mn + 5m (ordenado que así):

5m-7mn+12n

24m 2 n – 2mn – 12m 2 n – m3 =

48mn - 2mn-24mn-3m

22mn-4m = -4m+22mn
