\n" ); document.write( " $\"%282x%2B5%29%5E-1=%28x%2B4%29%5E-1\"$
\n" ); document.write( "since they are both to the -1 power, step 1 - raise them both to the 1st power and we get
\n" ); document.write( " $\"2x%2B5+=+x+%2B+4\"$
\n" ); document.write( "subtract x to get
\n" ); document.write( " $\"x+%2B+5+=+4\"$
\n" ); document.write( "subtract 5 to get
\n" ); document.write( " $\"x+=+-1\"$ \n" ); document.write( "
