Question 1201962
Choosing the variables differently, and following the description
<pre>
small bowl           c
large bowl           12
lid                  x
</pre>

The description then gives  {{{system(12+x=2c,c+x=12+(1/3)12)}}}


{{{system(12+x=2c,c+x=16)}}}


{{{system(2c-x=12,c+x=16)}}}-----------VERY SIMPLE TO SOLVE (STEPS ARE STRAIGHTFORWARD!)

These result values check as correct.
{{{system(x=6&2/3,and,c=9&1/3)}}}
