Question 1148211
You left out the question. How old are they now??
Let {{{ x }}} = Ali's age now
Erika's age is {{{ 5x }}}
---------------------------------
{{{ 5x + 4 = 3*( x + 4 ) }}}
{{{ 5x + 4 = 3x + 12 }}}
{{{ 2x = 8 }}}
{{{ x = 4 }}}
and
{{{ 5x = 20 }}}
------------------
Erika is 20
Ali is 4
------------------
check:
{{{ 5x + 4 = 3*( x + 4 ) }}}
{{{ 5*4 + 4 = 3*8 }}}
{{{ 20 + 4 = 24 }}}
{{{ 24 = 24 }}}
OK
