Question 979979
(1) {{{ J = 4L }}}
(2) {{{ j - 3 + L - 3 = 24 }}}
-------------------------
Substitute (1) into (2)
(2) {{{ 4L - 3 + L - 3 = 24 }}}
(2) {{{ 5L = 24 + 6 }}}
(2) {{{ 5L = 30 }}}
(2) {{{ L = 6 }}}
and
(1) {{{ J = 4L }}}
(1) {{{ J = 4*6 }}}
(1) {{{ J = 24 }}}
--------------------
Jack is 24
Lacy is 6
------------------
check:
(2) {{{ j - 3 + L - 3 = 24 }}}
(2) {{{ 24 - 3 + 6 - 3 = 24 }}}
(2) {{{ 30 - 6 = 24 }}}
(2) {{{ 24 = 24 }}}
OK
