Question 1048597
The sum of the ages of Pam, Dion, 
and their three children, in years, is {{{ 5x - 99 }}}
{{{ x }}} = Dion's age
{{{ x - 5 }}} = Pam's age
----------------------
The sum of the ages of their children is:
{{{ 5x - 99 - x - ( x - 5 ) }}}
{{{ 5x - 99 - x - x + 5 }}}
{{{ 3x - 94 }}}
---------------
check the answer:
Suppose {{{ x = 40 }}} ( Dion is 30 )
The sum of all their ages is:
{{{ 5x - 99 = 5*40 - 99 }}}
{{{ 5x - 99 = 101 }}}
--------------------
Dion is {{{ 40 }}}
Pam is {{{ 35 }}}
---------------
The sum of the childrens ages is:
{{{ 101 - 40 - 35  = 26 }}}
and
{{{ 3x - 94 = 3*40 - 94 }}}
{{{ 3x - 94 = 120 - 94 }}}
{{{ 3x - 94 = 26 }}}
OK
That seems reasonable. They could be
13, 9, and 4
