2 x - y = 8 .............1
\n" ); document.write( "Value of tickets
\n" ); document.write( "7 x -3 y = 28 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 3
\n" ); document.write( "Multiply (2) by 1
\n" ); document.write( "6 x -3 y = 24
\n" ); document.write( "7 x -3 y = 28
\n" ); document.write( "Add the two equations
\n" ); document.write( "13 x = 52
\n" ); document.write( "/ 13
\n" ); document.write( "x = 4
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "2 x - y = 8
\n" ); document.write( "8 - y = 8
\n" ); document.write( " - y = 8 -8
\n" ); document.write( " - y = 0
\n" ); document.write( " y = 0
\n" ); document.write( "x= 4
\n" ); document.write( "y= 0
