A student weighs her hamsters two at a time.
Sandy and White Ears weigh 209g together.
Eq: N + W + 0 = 209
-------------------
White Ears and Sport weigh 223g together.
Eq: 0 + W + S = 223
-------------------
Sandy and Sport weigh 216g together.
Eq: N + 0 + S = 216
-----------------------
How much does each hamster weigh?
Solve the system of three equations in any way to get:
Sandy = 101g
White Ears = 108g
Sport = 115g
================
