Question 1093344
Call the numbers {{{ a }}} and {{{b }}}
(1) {{{ b - a = 57 }}}
(2) {{{ b + a = 183 }}}
----------------------
Add the equations
{{{ 2b = 240 }}}
{{{ b = 120 }}}
and
(2) {{{ 120 + a = 183 }}}
Subtract {{{ 120 }}} from both sides of (2)
(2) {{{ a = 63 }}}
and
The numbers are 63 and 120
