Question 1020064
Let {{{ m }}} = Maya's age now
Let {{{ f }}} = father's age now
--------------------------
(1) {{{ f = 4*( m - 3 ) }}}
(2) {{{ f = 36 }}}
-------------------
(1) {{{ 36 = 4*( m - 3 ) }}}
(1) {{{ 36 =4m - 12 }}}
(1) {{{ 4m = 48 }}}
(1) {{{ m = 12 }}}
Maya is 12 now
--------------
check:
(1) {{{ f = 4*( m - 3 ) }}}
(1) {{{ 36 = 4*( 12 - 3 ) }}}
(1) {{{ 36 = 4*9  }}}
(1) {{{ 36 = 36 }}}
OK
