\n" ); document.write( "Total tickets sold
\n" ); document.write( "1.00 x + 1.00 y = 1,050.00 .............1
\n" ); document.write( "Value of tickets
\n" ); document.write( "6.00 x + 3.00 y = 4,200.00 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -3.00
\n" ); document.write( "Multiply (2) by 1.00
\n" ); document.write( "-3.00 x \ -3.00 y = -3,150.00
\n" ); document.write( "6.00 x + 3.00 y = 4,200.00
\n" ); document.write( "Add the two equations
\n" ); document.write( "3.00 x = 1,050.00
\n" ); document.write( "/ 3.00
\n" ); document.write( "x = 350.00
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "1.00 x + 1.00 y = 1,050.00
\n" ); document.write( "350.00 + y = 1,050.00
\n" ); document.write( " y = 1,050.00-350
\n" ); document.write( " y = 700.00
\n" ); document.write( " y = 700.00
