Question 538620
the container that holds the water for the football team is 1/2 full. after pouring out 3 gallons of water, it is 1/3 full.how many gallons can the container hold?
<pre>
Suppose it holds x gallons.  Then: 

              {{{(matrix(5,1,ONE, HALF, of, x, gallons))}}} - {{{(matrix(2,1,3, gallons))}}} = {{{(matrix(5,1,ONE, THIRD, of, x, gallons))}}}


                         {{{1/2}}}x - 3 = {{{1/3}}}x

Solve that and get 18 gallons.
