No need to solve for number of tickets sold. The description gives x=200.

You can solve for s, how many student tickets and y, how many adult tickets.
system%283s%2B6y=840%2Cs%2By=200%29

system%28s%2B2y=280%2Cs%2By=200%29

Subtract the two equations
highlight%28y=80%29
and highlight%28s=120%29.

kyle was in charge of ticket sales for the upcoming track meet. the cost of tickets was $3 for students and $6 for adults they collected $840 from tickets sales there were a total of 200 tickets sold . use x for the amount of students tickets sold . write an expression for the amount of adult tickets sold 
With x being the number of student tickets sold, number of adult tickets sold is: highlight_green%28200+-+x%29
