x= number of kids
\n" ); document.write( "y= number of adults
\n" ); document.write( "
\n" ); document.write( "1.00 x -1.00 y = 6.00 .............1
\n" ); document.write( "Total value
\n" ); document.write( "3.50 x + 7.50 y = 65.00 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 7.50
\n" ); document.write( "Multiply (2) by 1.00
\n" ); document.write( "7.50 x -7.50 y = 45.00
\n" ); document.write( "3.50 x + 7.50 y = 65.00
\n" ); document.write( "Add the two equations
\n" ); document.write( "11.00 x = 110.00
\n" ); document.write( "/ 11.00
\n" ); document.write( "x = 10.00
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "1.00 x -1.00 y = 6.00
\n" ); document.write( "10.00 -1.00 y = 6.00
\n" ); document.write( " -1.00 y = 6.00 -10
\n" ); document.write( " -1.00 y = -4.00
\n" ); document.write( " y = 4.00
\n" ); document.write( "x= 10.00 number of kids
\n" ); document.write( "y= 4.00 number of adults
