Question 174932
Find {{{matrix(1,3, "h(",4,")")}}} given that {{{matrix(1,5, "h(",x,")","=",x/2-7)}}}
<pre><font size = 4 color = "indigo"><b>
{{{matrix(1,5, "h(",x,")","=",x/2-7)}}}

Erase all the {{{x}}}'s

{{{matrix(1,6, "h(","","",")","=",""/2-7) }}}

Put {{{4}}}'s where the {{{x}}}'s were:

{{{matrix(1,5, "h(",4,")","=",4/2-7)}}}

Simplify the right side:

{{{matrix(1,5, "h(",4,")","=",2-7)}}}

{{{matrix(1,5, "h(",4,")","=",-5)}}}

Easy, wasn't it?
