Question 426990
Let {{{t}}} = Tim's age now
Let {{{c}}} = Coach's age now
-----------------------
given:
(1) {{{ c - 3 = 2*(t - 3) }}}
(2) {{{ c = t + 10 }}}
----------------
Substitute (2) into (1)
(1) {{{ t + 10 - 3 = 2*(t - 3) }}}
(1) {{{ t + 7 = 2t - 6 }}}
(1) {{{ t = 13 }}}
Tim is 13 now
check:
(1) {{{ c - 3 = 2*(t - 3) }}}
{{{ c - 3 = 2*(13 - 3) }}}
{{{ c = 20 + 3 }}}
{{{ c = 23 }}}
This is 10 years older than Tim is now
