Question 1063041
(1) Let {{{ n }}} = number of years from
now when father's age is twice son's age
{{{ 37 + n = 2*( 10 + n ) }}}
{{{ 37 + n = 20 + 2n }}}
{{{ n = 37 - 20 }}}
{{{ n = 17 }}}
In 17 yrs, father's age is twice son's age
-----------------------
check:
{{{ 10 + 17 = 27 }}}
and
{{{ 37 + 17 = 54 }}}
{{{ 54 = 2*27 }}}
{{{ 54 = 54 }}}
OK
