Question

A+b+c=524
A+b=229
B+c=229

A,b,c=¿.

Answer 1

A+b+c=524

A+b=229

B+c=229

rezulta ca c= 524- (a+b)= 524-229
c= 295
rezulta ca b= 229-295
b = -66
rezulta ca a = 229-(-66), a =229+66
a= 295

Answer 2

$a+b+c=524 \\ a+229=524 \\ \underline{a=295} \\ a+b=229 \\ Dacă \: \: a+b=229=b+c , \: atunci:\\ \implies a=c=295 \\ \implies \underline{c=295} \\ \implies b+c=229\\ \implies b+295=229 \\ \implies\underline{ b=4 }$
