x First Class
\n" ); document.write( "y Coach class
\n" ); document.write( "Total passengers
\n" ); document.write( "1 x + 1 y = 79 .............1
\n" ); document.write( "Total fare for all passengers
\n" ); document.write( "85 x + 60 y = 5290.00 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -60
\n" ); document.write( "Multiply (2) by 1
\n" ); document.write( "-60 x -60 y = -4740
\n" ); document.write( "85 x + 60 y = 5290
\n" ); document.write( "Add the two equations
\n" ); document.write( "25 x = 550
\n" ); document.write( "/ 25
\n" ); document.write( "x = 22
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "1 x + 1 y = 79
\n" ); document.write( "22 + y = 79
\n" ); document.write( " y = 79 -22
\n" ); document.write( " y = 57

\n" ); document.write( "22 First Class passengers
