5 x -9 y = 10 .............1
\n" ); document.write( "Total value
\n" ); document.write( "2 x + 3 y = 12 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 1
\n" ); document.write( "Multiply (2) by 3
\n" ); document.write( "5 x -9 y = 10
\n" ); document.write( "6 x + 9 y = 36
\n" ); document.write( "Add the two equations
\n" ); document.write( "11 x = 46
\n" ); document.write( "/ 11
\n" ); document.write( "x = 4 1/6
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "5 x -9 y = 10
\n" ); document.write( "20 8/9 -9 y = 10
\n" ); document.write( " -9 y = 10 -20 8/9
\n" ); document.write( " -9 y = -10 8/9
\n" ); document.write( " y = 1 2/9
\n" ); document.write( " \n" ); document.write( "

\n" );
