The answer doesn't make sense. If gus gives joe two it works but if joe gives gus two it doesn't.

It makes perfect sense. If gus gives joe 2 then gus has 8 and joe has 16. 8 x 2 = 16. If joe gives gus 2, then joe has 12 and gus has 12, 12 = 12

I never did figure this one correctly. The guys at work took about 15 mins to get it. Excellent job Missie!!

I should take that long to get.

g + 2 = j - 2
g = j - 4

2(g - 2) = j + 2
2g - 4 = j + 2
2(j - 4) - 4 = j + 2
2j - 8 - 4 = j + 2
j = 14

g = j - 4
g = 10

Therefore Joe had 14 and Gus had 10.

If Jo give 2 to be equal then he goes down 2 and Gus goes up 2 so Jo has 4 more than Gus. If Gus gives 2 he goes down 2 and Jo goes up 2 so Jo now has 8 more than Gus which is double so he has 16. So before the last pigs were given Gus had 14 and Jo had 10.

Sorry - other way round (I think)!
