\n" ); document.write( "1st Hint:
\n" ); document.write( "One setup equation would be \"1%2Fx+%2B+1%2F%28x%2B9%29+=+5%2F12\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2nd hint:
\n" ); document.write( "Multiply both sides by the LCD 12x(x+9) to arrive at \"12%28x%2B9%29+%2B+%2812x%29+=+5x%28x%2B9%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "3rd hint:
\n" ); document.write( "Expand everything out and get terms to one side.
\n" ); document.write( "You should get \"5x%5E2%2B21x-108=0\"
