You can put this solution on YOUR website!
\"One eighth of the square root of 7 less than a number is 2\" can be written:
\n" ); document.write( "Let n equal the number:
\n" ); document.write( " $\"%281%2F8%29%28n-sqrt%287%29%29+=+2\"$ Multiply both sides by 8.
\n" ); document.write( " $\"%28n-sqrt%287%29%29+=+16\"$ Now add $\"sqrt%287%29\"$ to both sides.
\n" ); document.write( " $\"n+=+16%2Bsqrt%287%29\"$ ...and, if you need an approximate value for n, then take the square root of 7 (an irrational number):
\n" ); document.write( " $\"n+=+16%2B2.6457\"$
\n" ); document.write( " $\"n+=+18.6457\"$ Approximately.
\n" ); document.write( "Or is it:
\n" ); document.write( " $\"%281%2F8%29%28sqrt%28n-7%29%29+=+2\"$ ??? then use Checkley's answer! \n" ); document.write( "

\n" );
