Question 1062027
Let {{{ n }}} = the number of years when 
Raymond will be 1/2 his dad's age
---------------------------------------
{{{ 16 + n = (1/2)*( 37 + n ) }}}
{{{ 2*( 16 + n ) = 37 + n }}}
{{{ 32 + 2n = 37 + n }}}
{{{ n = 37 - 32 }}}
{{{ n = 5 }}}
In 5 years
-----------------------------
check:
{{{ 16 + n = (1/2)*( 37 + n ) }}}
{{{ 16 + 5 = (1/2)*( 37 + 5 ) }}}
{{{ 21 = (1/2)*42 }}}
{{{ 42 = 42 }}}
OK
