x= No of kids
\n" ); document.write( "y= No of adults
\n" ); document.write( "
\n" ); document.write( "1.00 x -1.00 y = 8.00 .............1
\n" ); document.write( "
\n" ); document.write( "3.00 x + 7.50 y = 45.00 .............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 = 60.00
\n" ); document.write( "3.00 x + 7.50 y = 45.00
\n" ); document.write( "Add the two equations
\n" ); document.write( "10.50 x = 105.00
\n" ); document.write( "/ 10.50
\n" ); document.write( "x = 10.00
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "1.00 x -1.00 y = 8.00
\n" ); document.write( "10.00 -1.00 y = 8.00
\n" ); document.write( " -1.00 y = 8.00 -10
\n" ); document.write( " -1.00 y = -2.00
\n" ); document.write( " y = 2.00 1
\n" ); document.write( "x= 10 No of kids
\n" ); document.write( "y= 2 No of adults
