Thanks a lot for the help, I really appreciate it! :smile:

Argh, I'm not thinking straight, bouncing between two assignments. I meant 291 - 38.

Yeah, I know it's just one of the many possibilities I know of. I did 298 - 25 - 38 to get it.

253 empty boxes L = 18 M = 20 Thanks :D

l + m = 38?

m + l

An expression that doesn't change. The calculation would be: (6(L + M) + 25) - (7(L + M) + 25) But I don't know what the outcome would be.

t - e is the invariant.

It works, I have no clue on how to solve two variable equations. Couldn't find anything helpful on the net either.

7L + 7M + 25 = 291 = {-25 from each side} 7L + 7M = 266 = {let L be 18} (7*18) + 7M = 266 = {Simplify} 126 + 7M = 266 = {-126 from each side} 7M = 140 = {140 / 7 = M} M = 20 L = 18 M = 20

7l + 7m + 25

(7l) + 25

Which leaves enough space for 13 medium boxes to be filled with small boxes.

(7*25) + 25 = 200

trial and error 25 + 6(18+21) = 259
