Question 993298
  Ann and Beth weighed 119 kg
• Beth and Celine weighed 112 kg
• Celine and Ann weighed 115 kg
How much did each of the girls weigh?
---------
A + B = 119
B + C = 112
C + A = 115
----------------
Note:
B = 112-C
A = 115-C
-----
Substitute for A and for B ; then solve for "C"::
115-C + 112-C = 119
-2C + 227 = 119
---
-2C = -108
C = 54 lbs
----
A = 112-54 = 58 lbs
A = 115-54 = 61 lbs
