x= Number of adults
\n" ); document.write( "y= Number of students
\n" ); document.write( "Total tickets
\n" ); document.write( "1 x + 1 y = 110 .............1
\n" ); document.write( "Total value
\n" ); document.write( "9 x + 5 y = 650 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -5
\n" ); document.write( "Multiply (2) by 1
\n" ); document.write( "-5 x -5 y = -550
\n" ); document.write( "9 x + 5 y = 650
\n" ); document.write( "Add the two equations
\n" ); document.write( "4 x = 100
\n" ); document.write( "/ 4
\n" ); document.write( "x = 25
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "1 x + 1 y = 110
\n" ); document.write( "25 + y = 110
\n" ); document.write( " y = 110 -25
\n" ); document.write( " y = 85
\n" ); document.write( " y = 85
\n" ); document.write( "x= 25 Number of adults
\n" ); document.write( "y= 85 Number of students
