x + y = -1
\n" ); document.write( "so
\n" ); document.write( "x = -y-1
\n" ); document.write( ".
\n" ); document.write( "4x -2y = -16
\n" ); document.write( ".
\n" ); document.write( "substitute
\n" ); document.write( ".
\n" ); document.write( "4(-y -1) -2y = -16
\n" ); document.write( ".
\n" ); document.write( "-4y -4 -2y = -16
\n" ); document.write( ".
\n" ); document.write( "-6y = -12
\n" ); document.write( ".
\n" ); document.write( "y = 2
\n" ); document.write( ".
\n" ); document.write( "x + y = -1
\n" ); document.write( ".
\n" ); document.write( "x + 2 = -1
\n" ); document.write( ".
\n" ); document.write( "x = -3
\n" ); document.write( ".
\n" ); document.write( "Answer: x = -3, y = 2
