2(x +y) +8 =0
\n" ); document.write( "2x + 2y + 8 = 0
\n" ); document.write( "2x = -2y - 8
\n" ); document.write( "x = -y - 4
\n" ); document.write( "-------------------------------------------------------------
\n" ); document.write( "6x + 4y =-28
\n" ); document.write( "6(-y - 4) +4y= -28
\n" ); document.write( "-6y - 24 + 4y = -28
\n" ); document.write( "-2y = -4
\n" ); document.write( "y = 2
\n" ); document.write( "-------------------------------------------
\n" ); document.write( "2x + 2y + 8 = 0
\n" ); document.write( "2x + 4 + 8 = 0
\n" ); document.write( "2x = -12
\n" ); document.write( "x = -6
\n" ); document.write( "*perpendicular due to different slopes*
\n" ); document.write( "(-6,2)
\n" ); document.write( "(independent,consistent) \n" ); document.write( "

\n" );
