Question 613661
All we have to do is substitute what we know in. {{{2(3)+3(3)-1(3)-3(2)(3)(-1)}}}. That might look a little intimidating, but let's take it one step at a time:
{{{6+3(3)-1(3)-3(2)(3)(-1)}}}
{{{6+9-1(3)-3(2)(3)(-1)}}}
{{{6+9-3-3(2)(3)(-1)}}}
{{{6+9-3-6(3)(-1)}}}
{{{6+9-3-18(-1)}}}
{{{6+9-3+18}}}
{{{15-3+18}}}
{{{15+15}}}
{{{30}}}

<p>Your final answer is <b>30</b>. :)
