3x-y=2x-7
\n" ); document.write( "-y=2x-3x-7
\n" ); document.write( "-y=-x-7
\n" ); document.write( "y=x+7 (red line)
\n" ); document.write( "2x+5=2y-9
\n" ); document.write( "-2y=-2x-9-5
\n" ); document.write( "-2y=-2x-14
\n" ); document.write( "y=-2x-2-14/-2
\n" ); document.write( "y=x+7 (green line)
\n" ); document.write( "These lines are the same.
