Question 1207996
<pre>
Vivian and her brother had some money.

Suppose Vivian had V dollars and her brother had B dollars.

After spending 2/5 of his B dollars, her brother had B-(2/5)B = (3/5)B = 78 dollars left. 

{{{expr(3/5)B=78}}}
{{{3B=390}}}
{{{B=130}}}


Vivian spent 1/3 of her V dollars and had V-(1/3)V = (2/3)V, the same amount of
money as her brother, which was 78 dollars. So 

{{{expr(2/3)V=78}}}
{{{2V=234}}}
{{{V=117}}}

So in the beginning, Vivian had $117 and her brother had $130.
