But that's really strange because you have a decimal number of cards and I would expect ti to be a whole number.
OpenStudy (anonymous):
it*
OpenStudy (anonymous):
I thought it would be x+3x=68
OpenStudy (anonymous):
Are you SURE it was 68 cards and not 69?
OpenStudy (anonymous):

Wait.
OpenStudy (anonymous):
Caleb is correct.
OpenStudy (anonymous):
x=bills cards
3x=bobs cards
add them you get 68
OpenStudy (anonymous):
Because the sum of their cards is 68.
OpenStudy (anonymous):
then would the answer be 17?
