A+B = 200 & A+B+C = 240, so C = 40

B+C = 60 & C = 40, so B = 20

A+B = 200 & B = 20, so A = 180

A + B + C = 240

but B + C = 60

so, A + (B+C) = 240
A + 60 = 240
A = 240-60
A = 180

A + B = 200
B + C = 60
A+B+C = 240

B = 200 - A
C = 60 - b

A + (200-A) + (60-b) = 240
260 - b = 240
-b = -20
b = 20
A + 20 = 200
-20 -20
A = 180
