Question 889615
just write an equation for what it says
:
 the product of two more than a number and three times the reciprocal of the number is 15/4.
(n+2) * {{{3/n}}} = {{{15/4}}}
We can write it
{{{(3(n+2))/n}}} = {{{15/4}}}
cross multiply
12(n+2) = 15n
12n + 24 = 15n
24 = 15n - 12n
24 = 3n
n = 24/3
n = 8
:
;
see if that works
(8+2) * {{{3/8}}} = {{{15/4}}}
{{{30/8}}} = {{{15/4}}}
