$\"+L+=+a%2B%28n-1%29%2Ad+\"$
\n" ); document.write( "Subtract a from both sides:
\n" ); document.write( " $\"+L-a+=+%28n-1%29%2Ad+\"$
\n" ); document.write( "Divide by n-1 on both sides:
\n" ); document.write( " $\"++%28L-a%29%2F%28n-1%29+=+d+\"$ \r
\n" ); document.write( "\n" ); document.write( "Re-writing with d on left hand side:
\n" ); document.write( " $\"+d+=+%28L-a%29%2F%28n-1%29+\"$ with the restriction $\"+n+%3C%3E+1+\"$ \n" ); document.write( "
