The Father will always be 25 year older than his Son
Let {{{ f }}} = Father's age now
Let {{{ s }}} = Son's age now
given:
(1) {{{ f = s + 25 }}}
(2) {{{ f = 3s + 7 }}}
By substitution:
{{{ s + 25 = 3s + 7 }}}
{{{ 2s = 18 }}}
{{{ s = 9 }}}
and
(1) {{{ f = s + 25 }}}
(1) {{{ f = 9 + 25 }}}
(10 {{{ f = 34 }}}
The Father's age is 34
