Let {{{ x }}} = her age now
{{{ x + 12 }}} = her age in 12 yrs
{{{ x - 32 }}} = her age 32 yrs ago
-------------------------------
given:
{{{ x + 12 = 3*( x - 32 ) }}}
{{{ x + 12 = 3x - 96 }}}
{{{ 2x = 108 }}}
{{{ x = 54 }}}
She is 54
-------------
check:
{{{ x + 12 = 3*( x - 32 ) }}}
{{{ 54 + 12 = 3*( 54 - 32 ) }}}
{{{ 66 = 3*22 }}}
{{{ 66 = 66 }}}
Ok
