x= cost of adult tickets
\n" ); document.write( "y= cost of student tickets
\n" ); document.write( "Total sold
\n" ); document.write( "7 x + 11 y = 234 .............1
\n" ); document.write( "Total value
\n" ); document.write( "14 x + 4 y = 234 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -4
\n" ); document.write( "Multiply (2) by 11
\n" ); document.write( "-28 x -44 y = -936
\n" ); document.write( "154 x + 44 y = 2574
\n" ); document.write( "Add the two equations
\n" ); document.write( "126 x = 1638
\n" ); document.write( "/ 126
\n" ); document.write( "x = 13
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "7 x + 11 y = 234
\n" ); document.write( "91 + 11 y = 234
\n" ); document.write( " 11 y = 234 -91
\n" ); document.write( " 11 y = 143
\n" ); document.write( " y = 13
\n" ); document.write( "x= 13 cost of adult tickets
\n" ); document.write( "y= 13 cost of student tickets
