Answer:

5/12k = 29/36m

8b = 10w

9z = 15

Explanation:

Combining the like terms in these sets of equations is quite easy and straightforward. All we do is carry the like terms to either of the side of the equation, and question is solved. As in below

1/4k + 1/4m - 2/3k + 5/9m =

1/4k - 2/3k + 1/4m + 5/9m = 0

-5/12k + 29/36m = 0

5/12k = 29/36m

-4b + 2w + (-4b) + 8w =

-4b - 4b + 2w + 8w = 0

-8b + 10w = 0

8b = 10w

6- 5z + 8 - 4z + 1​ =

6 + 8 + 1 - 5z - 4z = 0

15 - 9z = 0

9z = 15
