By looking at it, I see:
\n" ); document.write( " $\"+x%5E2++-+6x%2Ay+%2B+9y%5E2+=+25+\"$
\n" ); document.write( " $\"+%28+x+-+3y+%29%5E2+=+5%5E2+\"$
\n" ); document.write( "Take the square root of both sides
\n" ); document.write( " $\"+x+-+3y+=+5+\"$
\n" ); document.write( "and
\n" ); document.write( " $\"+x+-+3y+=+-5+\"$
\n" ); document.write( "-----------------
\n" ); document.write( " $\"+3y+=+x+-+5+\"$
\n" ); document.write( "(1) $\"+y+=+%281%2F3%29%2Ax+-+5%2F3+\"$
\n" ); document.write( "and also:
