You can put this solution on YOUR website!
a, adults
c, children

system%28a%2Bc=619%2C3a%2Bc=1150%29

The convenient way to continue is Eliminate c, solving first for a.
%283a%2Bc%29-%28a%2Bc%29=1150-619
2a=531
but this makes no sense. Whole and EVEN number for a will be needed. There cannot be any HALF of an adult. Recheck your problem description.
