Question 543028
Call the numbers {{{a}}} and {{{b}}}
given:
(1) {{{ a + b = 51 }}}
(2) {{{ a/b = 13 }}}
------------
(2) {{{ a = 13b }}}
Substitute (2) into (1)
(1) {{{ 13b + b = 51 }}}
(1) {{{ 14b = 51 }}}
(1) {{{ b = 51/14 }}}
and, since
(1) {{{ a + b = 51 }}}
(1) {{{a + 51/14 = 51 }}}
(1) {{{ a = 51 - 51/14 }}}
(1) {{{ a = 51*( 1 - 1/14 ) }}}
(1) {{{ a = ( 51*13 )/14 }}}
