Question 908429
Let {{{ j }}} = Jack's age now
Let {{{ f }}} = father's age now
---------------------------
Note that the difference in their ages
will always be {{{ 29 }}} years
so, I can say:
{{{ f + j = 53 }}}
{{{ f - j = 29 }}}
--------------
Add the equations:
{{{ 2f = 82 }}}
{{{ f = 41 }}}
and, since
{{{ f + j = 53 }}}
{{{ 41 + j = 53 }}}
{{{ j = 12 }}}
The father is 41
Jack is 12
