Question 1122227
{{{((15/x)-5)/(x-3)}}}, simplify with rationalizing and substitute in 3 for x. The answer key says it is {{{-5/3}}} but I don’t know how to get there
<pre>As it is now, {{{matrix(1,3, x <> 0, and, x <> 3)}}}
However, SIMPLIFYING the expression will result in: {{{- 5/x}}}.
When 3 is substituted for x in this SIMPLIFIED FORM, you'll get: {{{highlight_green(- 5/3)}}}
