Question 1187372
<pre>
                Sandra           Ted            Justina
total            x               t               j                     377
first xfers      x-15            t+13           j+15-13=j+2
</pre>


{{{system((x-15)/(t+13)=4/3,(x-15)/(j+2)=3/2)}}}


{{{system(3(x-15)=4(t+13),2(x-15)=3(j+2))}}}
{{{also}}} {{{x+t+j=377}}}
