solve by elimination x+y=-2 and -x+13y=14
\n" ); document.write( ".
\n" ); document.write( "Add both equations together:
\n" ); document.write( " x+ y=-2
\n" ); document.write( "-x+13y=14
\n" ); document.write( "-------------
\n" ); document.write( " 14y = 12
\n" ); document.write( " y = 12/14
\n" ); document.write( " y = 6/7
\n" ); document.write( ".
\n" ); document.write( "to find x, substitute the above into:
\n" ); document.write( "x+y=-2
\n" ); document.write( "x+6/7=-2
\n" ); document.write( "x=-2-6/7
\n" ); document.write( "x=-14/7-6/7
\n" ); document.write( "x = -20/7
\n" ); document.write( ".
\n" ); document.write( "solution:
\n" ); document.write( "x= -20/7
\n" ); document.write( "y= 6/7
\n" ); document.write( " \n" ); document.write( "
