Adult(A) = 16
\n" ); document.write( "Child (C) = 9
\n" ); document.write( "Total tickets sold = 24
\n" ); document.write( "Total collected = $258
\n" ); document.write( "\"+A+%2B+C+=+24+\"
\n" ); document.write( "solve for A
\n" ); document.write( "\"+A+=+24+-+C+\"
\n" ); document.write( "Substitute this into the next equation
\n" ); document.write( "\"+16A+%2B+9C+=+%24258+\"
\n" ); document.write( "\"+16%2824-C%29+%2B+9C+=+%24258+\"
\n" ); document.write( "Distribute
\n" ); document.write( "\"+384+-+16C+%2B+9C+=+258+\"
\n" ); document.write( "Combine like terms
\n" ); document.write( "\"+384+-+7C+=+258+\"
\n" ); document.write( "subtract 384 from both sides
\n" ); document.write( "\"+-7C+=+-126+\"
\n" ); document.write( "Divide by -7
\n" ); document.write( "\"+C+=+18+\"
\n" ); document.write( "This is what you were solving for in the first place\r
