Question 1132725
Let {{{ 2x }}} = Joel's age now
{{{ x }}} = Kayla's age now
--------------------------------------
I think they want 1 equation with 1 unknown, so
{{{ x + 5 + 2x + 5 = 55 }}}
{{{ 3x + 10 = 55 }}}
{{{ 3x = 45 }}}
{{{ x = 15 }}}
and
{{{ 2x = 30 }}}
Joel is 30
Kayla is 15
---------------------
check:
{{{ 3*15 + 10 = 55 }}}
{{{ 55 = 55 }}}
OK
