Question 177557
let the weight of tweedledee and tweedledum be a and be respectively
:
a+2b=361.....eq 1
b+2a=362.....eq 2
:
multiply eq 1 by -2 and add equations together.
:
-2a-4b=-722.....revised eq 1
b+2a=362........eq 2
:
 The a terms will be eliminated because -2a+2a=0. We are left with -4b+b=-722+362
:
-3b=-360
:
{{{highlight(b=120)}}}tweedledum's weight
:
take b's found value and plug it back into any equation and solve for a
:
I choose eq 1. a+2(120)=361--->a=361-240=121
:
{{{highlight(a=121)}}}tweedledee's weight
