x= number of $1 tickets
\n" ); document.write( "y= number of $0.5 tickets
\n" ); document.write( "
\n" ); document.write( "1.00 x + 1.00 y = 3600.00 .............1
\n" ); document.write( "Total value
\n" ); document.write( "1.00 x 0.50 y = 2225.00 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -0.50
\n" ); document.write( "Multiply (2) by 1.00
\n" ); document.write( "-0.50 x -0.50 y = -1800.00
\n" ); document.write( "1.00 x + 0.50 y = 2225.00
\n" ); document.write( "Add the two equations
\n" ); document.write( "0.50 x = 425.00
\n" ); document.write( "/ 0.50
\n" ); document.write( "x = 850.00
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "1.00 x + 1.00 y = 3600.00
\n" ); document.write( "850.00 + y = 3600.00
\n" ); document.write( " y = 3600.00 -850.00
\n" ); document.write( " y = 2750.00
\n" ); document.write( " y = 2750.00
\n" ); document.write( "x= 850 number of $1 tickets
\n" ); document.write( "y= 2750 number of $0.5 tickets
