Question

anonymous · Answer

We can call a the number of adults
and c the number of children

so the equations would be

a+c=52
3a=c

any idea how to solve?

anonymous · Answer

solve for c right?

anonymous · Answer

Sorry to but in, but wouldn't the first equation be 3a+c=52?

anonymous · Answer

I mean a+3c=52 ?

anonymous · Answer

Thats the total number of people, adults+children=52

anonymous · Answer

Oh OK sorry

anonymous · Answer

It's ok, 

yes solve for c using substitution or elimination @tpenn
