Let the prices of senior and student tickets be x and y. Then we have
\n" ); document.write( "10x + 3y = 57 and
\n" ); document.write( "5x + 11y = 114
\n" ); document.write( "Now multiply this second equation by two and subtract from the first and we get
\n" ); document.write( "10x + 3y = 57
\n" ); document.write( "-(10x + 22y = 228)
\n" ); document.write( "---------------------
\n" ); document.write( "-19y = - 171
\n" ); document.write( "y = 9 dollar student tickets
\n" ); document.write( "Substituting back into the first equation gives
\n" ); document.write( "10x + 3(9) = 57
\n" ); document.write( "10x + 27 = 57
\n" ); document.write( "10x = 30
\n" ); document.write( "x = 3 dollar senior tix
\n" ); document.write( "
\n" ); document.write( "
