2 x + 1 y = 7 .............1
\n" ); document.write( "1 x -3 y = 5 .............2
\n" ); document.write( "
\n" ); document.write( "multiply (1)by 3
\n" ); document.write( "Multiply (2) by 1
\n" ); document.write( "6 x + 3 y = 21
\n" ); document.write( "1 x -3 y = 5
\n" ); document.write( "Add the two equations
\n" ); document.write( "7 x = 26
\n" ); document.write( "/ 7
\n" ); document.write( "x = 3.71 OR 26/7
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "2 x + 1 y = 7
\n" ); document.write( "7.43 + 1 y = 7
\n" ); document.write( " 1 y = 7 -7.43
\n" ); document.write( " 1 y = -0.43
\n" ); document.write( " y = -0.43OR - 3/7
\n" ); document.write( " \n" ); document.write( "
\n" );
