Answer 2

- Solución:

a) 3x - 5x =

-2x

b) 6h + 3h - 11h =

9h - 11h =

-2h

c) k + 7k - 3k + 2k =

8k - 3k + 2k =

5k + 2k =

7k

d) 1p + 8p - 7p + 2p =

9p - 7p + 2p =

2p + 2p =

4p

e) 60c - 5 - 40c - 3 =

60c - 40c - 5 - 3 =

20c - 8

f) -3d + 7d + 5 - 7 =

4d - 2

g) 1r + 7 - 5r - 7 =

1r - 5r + 7 - 7 =

-4r + 0 =

-4r

h) -6 + 3x - 5x + 4 =

-6 + 4 + 3x - 5x =

-2 - 2x
