3 x -1 y = 12 .............1
\n" ); document.write( "-2 x + 11 y = 5 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 11
\n" ); document.write( "Multiply (2) by 1
\n" ); document.write( "33 x -11 y = 132
\n" ); document.write( "-2 x 11 y = 5
\n" ); document.write( "Add the two equations
\n" ); document.write( "31 x = 137
\n" ); document.write( "/ 31
\n" ); document.write( "x =137/31
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "3 x + -1 y = 12
\n" ); document.write( "13.26 + -1 y = 12
\n" ); document.write( " -1 y = 12 -13.26
\n" ); document.write( " -1 y = -1.26
\n" ); document.write( " y =5/4
\n" ); document.write( " \n" ); document.write( "

\n" );
