Question 713077
Let {{{ t }}} = Tess's age now
Let {{{ j }}} =Jose's age now
given:
{{{ j = t + 5 }}}
{{{ j - 3 =2*( t - 3 ) }}}
------------------
By substitution:
{{{ t + 5 - 3 = 2*( t - 3 ) }}}
{{{ t + 2 = 2t - 6 }}}
{{{ t = 8 }}}
and, since
{{{ j = t + 5 }}}
{{{ j = 8 + 5 }}}
{{{ j = 13 }}}
-----------
Tess is 8 now
check:
{{{ j - 3 =2*( t - 3 ) }}}
{{{ 13 - 3 =2*( 8 - 3 ) }}}
{{{ 10 = 2*5 }}}
{{{ 10 = 10 }}}
OK
