Question 1092530
Let {{{ a }}} = weight in kg of a large box
Let {{{ b }}} = weight in kg of a small box
-------------------------------------
(1) {{{ 5a + 6b = 108 }}} kg
(2) {{{ 3a + 2b = 5 }}} kg
----------------------------
Multiply both sides of (2) by {{{ 3 }}}
and subtract (2) from (1)
(1) {{{ 5a + 6b = 108 }}}
(2) {{{ -9a - 6b = -15 }}}
------------------------
{{{ -4a = 93 }}}
{{{ a = -23.25 }}}
Answer can't be negative, are you sure the
numbers are right? 5 kg of total weight
looks suspicious.
