6x+12y=-6
\n" ); document.write( "/6
\n" ); document.write( "x+2y=-1\r
\n" ); document.write( "\n" ); document.write( "and 2x+5y=0\r
\n" ); document.write( "\n" ); document.write( "1 x + 2 y = -1 .............1
\n" ); document.write( "2 x + 5 y = 0 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -5
\n" ); document.write( "Multiply (2) by 2
\n" ); document.write( "-5 x -10 y = 5
\n" ); document.write( "4 x + 10 y = 0
\n" ); document.write( "Add the two equations
\n" ); document.write( "-1 x = 5.00
\n" ); document.write( "/ -1
\n" ); document.write( "x = -5
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "1 x + 2 y = -1
\n" ); document.write( "-5 + 2 y = -1
\n" ); document.write( " 2 y = -1 + 5
\n" ); document.write( " 2 y = 4
\n" ); document.write( " y = 2
\n" ); document.write( " \n" ); document.write( "
\n" );
