3 x + 5 y = 11 .............1
\n" ); document.write( "
\n" ); document.write( "1 x + 3 y = 13 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -3
\n" ); document.write( "Multiply (2) by 5
\n" ); document.write( "-9 x -15 y = -33
\n" ); document.write( "5 x + 15 y = 65
\n" ); document.write( "Add the two equations
\n" ); document.write( "-4 x = 32
\n" ); document.write( "/ -4
\n" ); document.write( "x = -8
\n" ); document.write( "plug x x in (1)
\n" ); document.write( "3 x + 5 y = 11
\n" ); document.write( "-24 + 5 y = 11
\n" ); document.write( " 5 y = 11 + 24
\n" ); document.write( " 5 y = 35
\n" ); document.write( " y = 7
\n" ); document.write( "x=-8,v=7 \n" ); document.write( "

\n" );
