Denise,
1 bag of corn weighs 10 lbs
2 bags of corn and 1 bag of oats weigh 26 pounds
So 1 bag of oat weighs 26-2*10 = 6 lbs
Let the wheat bag weigh w lbs
Wt of 3 bags of wheat + 2 bags of corn + 1 bag of oat = 3w + 2*10 + 6 = 3w + 26
Wt of 1 bag of wheat + 1 bag of corn + 5 bag of oats = w + 10 + 5*6 = w + 40
We know these weights are equal
3w + 26 = w + 40
2w = 14
w = 7
Bag of wheat weighs 7 lbs
