You can put this solution on YOUR website!
x= number of adult tickets
\n" ); document.write( "y= number of child tickets
\n" ); document.write( "Total tickets sold
\n" ); document.write( "1 x + 1 y = 49 .............1
\n" ); document.write( "
\n" ); document.write( "15 x + 8 y = 469 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -8
\n" ); document.write( "Multiply (2) by 1
\n" ); document.write( "-8 x -8 y = -392
\n" ); document.write( "15 x + 8 y = 469
\n" ); document.write( "Add the two equations
\n" ); document.write( "7 x = 77
\n" ); document.write( "/ 7
\n" ); document.write( "x = 11
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "1 x + 1 y = 49
\n" ); document.write( "11 + y = 49
\n" ); document.write( " y = 49 -11
\n" ); document.write( " y = 38
\n" ); document.write( " y = 38
\n" ); document.write( "x= 11 number of adult tickets
\n" ); document.write( "y= 38 number of child tickets
