(1) $\"+y+=+-6x+-+5+\"$

\n" ); document.write( "Plug (1) into (2)
\n" ); document.write( " $\"+-6x+-+5+=+-2x+-+1+\"$
\n" ); document.write( "Multiply both sides by $\"+-1+\"$
\n" ); document.write( " $\"+6x+%2B+5+=+2x+%2B+1+\"$
\n" ); document.write( "Subtract $\"+2x+\"$ from both sides
\n" ); document.write( " $\"+4x+%2B+5+=+1+\"$
\n" ); document.write( "Subtract $\"+5+\"$ from both sides
\n" ); document.write( " $\"+4x+=+-4+\"$
\n" ); document.write( " $\"+x+=+-1+\"$
\n" ); document.write( "--------------------
\n" ); document.write( "and

\n" ); document.write( "(2) $\"+y+=+2+-+1+\"$
\n" ); document.write( "(2) $\"+y+=+1+\"$
\n" ); document.write( "-------------------------------
\n" ); document.write( "The intersection is at ( -1, 1 )
\n" ); document.write( "-------------------------------
