Question 739474
If I add {{{ x/2 + 12 }}}, that is how old
Alex is now
If I add {{{ x/2 }}} to that, He will be {{{ 2x }}} yrs old
{{{ x/2 + 12 + x/2 = 2x }}}
{{{ x + 12 = 2x }}}
{{{ x = 12 }}}
------------
Right now, Alex is {{{ x/2 + 12 }}}
{{{ 12/2 + 12 = 18 }}}
{{{ 3x = 3*12 }}}
{{{ 3x = 36 }}}
{{{ 18 + 36 = 54 }}}
3x years from now Alex will be 54
