x Students tickets
\n" ); document.write( "y asb tickets
\n" ); document.write( "Total attended
\n" ); document.write( "1 x + 1 y = 324 .............1
\n" ); document.write( "
\n" ); document.write( "2.50 x + 1.25 y = 645 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -1.25
\n" ); document.write( "Multiply (2) by 1
\n" ); document.write( "-1.25 x -1.25 y = -405
\n" ); document.write( "2.50 x + 1.25 y = 645
\n" ); document.write( "Add the two equations
\n" ); document.write( "1.25 x = 240
\n" ); document.write( "/ 1.25
\n" ); document.write( "x = 192
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "x+y= 324
\n" ); document.write( "192+y=324
\n" ); document.write( " y = 324-192
\n" ); document.write( " y = 132
\n" ); document.write( "192 Students tickets
\n" ); document.write( "132 asb tickets
