Question 1151848
Let {{{ x }}} = Kate's age now
{{{ x + 5 }}} = Mayen's age now
----------------------------------
{{{ ( x + 5 ) + 6 = 3*( x - 3 ) }}}
{{{ x + 11 = 3x - 9 }}}
{{{ 2x = 20 }}}
{{{ x = 10 }}}
and
{{{ x + 5 = 15 }}}
----------------------
Kate is 10
Mayen is 15
-----------------
check:
In 6 yrs,
Kate will be 16
Mayen will be 21
--------------------
3 yrs ago, Kate was 7
3 times that is 21
Mayen was 21 also
OK
