Bent scale

Monica weighed 52 kg. Sara 54 kg. Together they weighed 111 kg. They noticed that the weight on the scale was bent. How much did they really weigh?

Correct result:

M =  57 kg
S =  59 kg

Solution:


M+x = 52
S+x = 54
M+S+x=111

M+x = 52
S+x = 54
M+S+x = 111

M = 57
S = 59
x = -5

Our linear equations calculator calculates it.
S=59=59 kg
