x is how many kids
y is how many adults

system%28x%2By=335%2C1.5x%2B4y=940%29

Various ways to go... Multiply the ticket count equation's members by 4 to prepare for elimination of y.

system%284x%2B4y=1340%2C1.5x%2B4y=940%29
%284x%2B4y%29-%281.5x%2B4y%29=1340-940
2.5x=400
x=4000%2F25
x=40%2A100%2F25
highlight%28x=160%29
highlight%28y=335-160=highlight%28175%29%29
