27+104=131

Answer 2

[tex]a+b+c=331 \\ a-x=64 \longrightarrow a=x+64 \\ b-x=82 \longrightarrow b=x+82 \\ c-x=104 \longrightarrow c=x+104 \\ x+64+x+82+x+104=331 \\ 3x+250=331 \\ 3x=331-250 \\ 3x=81 \\ x=81:3 \\ \underline{x=27} \Longrightarrow \boxed{a=64+27 =91} \\ ~~~~~~~~~~\Longrightarrow \boxed{b=82+27=109} \\ ~~~~~~~~~~\Longrightarrow \boxed{c=104+27=131}[/tex]
