Reading it that way is difficult. The description could be written better like this:

-
Theatre sells x adult's tickets for $20 each, and y children's tickets for $10 each. On one evening of a performance, 350 tickets were sold and the revenue for tickets was $5250 dollars.
-

System of Equations:
system%2820x%2B10y=5250%2Cx%2By=350%29

A simplification,
system%282x%2By=525%2Cx%2By=350%29
and you can easily eliminate y to quickly find x.
