Question 128396
Let the number be n.
{{{n-(1/8)sqrt(7) = 2}}} Add {{{(1/8)sqrt(7) }}} to both sides.
{{{n = 2+(1/8)sqrt(7)}}} Simplify.
{{{n = (16+sqrt(7))/8}}} This is the exact answer.
 For an approximate answer, take the square root of 7 (an irrational number).
{{{n = (16+2.646)/8}}}
{{{n = 2.33}}}Approximately.
