Let the number be n.
\n" ); document.write( " $\"n-%281%2F8%29sqrt%287%29+=+2\"$ Add $\"%281%2F8%29sqrt%287%29+\"$ to both sides.
\n" ); document.write( " $\"n+=+2%2B%281%2F8%29sqrt%287%29\"$ Simplify.
\n" ); document.write( " $\"n+=+%2816%2Bsqrt%287%29%29%2F8\"$ This is the exact answer.
\n" ); document.write( " For an approximate answer, take the square root of 7 (an irrational number).
\n" ); document.write( " $\"n+=+%2816%2B2.646%29%2F8\"$
\n" ); document.write( " $\"n+=+2.33\"$ Approximately.
\n" ); document.write( " \n" ); document.write( "
