2 x + 3 y = 1 .............1
\n" ); document.write( "Total value
\n" ); document.write( "5 x + 7 y = 3 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -7
\n" ); document.write( "Multiply (2) by 3
\n" ); document.write( "-14 x -21 y = -7
\n" ); document.write( "15 x + 21 y = 9
\n" ); document.write( "Add the two equations
\n" ); document.write( "1 x = 2
\n" ); document.write( "/ 1
\n" ); document.write( "x = 2
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "2 x + 3 y = 1
\n" ); document.write( "4 + 3 y = 1
\n" ); document.write( " 3 y = 1 -4
\n" ); document.write( " 3 y = -3
\n" ); document.write( " y = -1
\n" ); document.write( " \n" ); document.write( "

\n" );
