Let x=number of matches needed to fill each box.
Then 24x=total number of matches
When x-4 matches are put in each box, then we have a total of 28(x-4)matches
Soooo
28(x-4)=24x
28x-112=24x subtract 28x from each side
-4x=-112
x=28 number of matches needed to fill one box
CK
24*28=28*24
672=672
Hope this helps---ptaylor

Hi

Let x and (x-4) represent the number of matches filling 24 amd 28 boxes respectively

Note: the Total number of matches is the same filling the 24 and 28 boxes

 24x = 28(x-4)

solving for x

 24x = 28x - 112

 112 = 4x

  28 = x, the number in each of the 24 boxes

24*28 = 672 is the total number of matches



CHECKING our answer

  24boxes*28matches/box = 28boxes*24matches/box = 672
