X=weight of large box
y=weight of small box
so
3x+5y=135 and
9x+7y=279
eliminate x's
multiply first equation by -3 and add to 2nd
-9x-15y=-405
<u>9x+7y=279 +</u>
0x-8y=-126
-8y=-126
divide both sides by 8
y=15.75
sub back to find x
3x+5y=135
3x+5(15.75)=135
3x+78.75=135
3x=56.25
divide both sides by 3
x=18.75
each large box weighs 18.75kg
each small box weighs 15.75kg
