Ta có: a + b + b + c = 184 + 97 => a + 2b + c = 281
Ta có: (a + 2b + c) - ( a + b + c) = 281 - 259 = a + 2b + c - a - b - a = b = 22 (1)
Ta có: a + b = 184 mà b = 22(cmt) => a = 162
=> c = 259 - 162 - 22 = 75
\((a+b+c)-(a+b)=c\)
\(\Rightarrow259-184=c\)
\(\Rightarrow75=c\)
\((a+b+c)-(b-c)=a\)
\(\Rightarrow259-97=c\)
\(\Rightarrow162=c\)
\((a+b+c)-(b+c)=a\)
\(\Rightarrow259-(75+162)=a\)
\(\Rightarrow22=a\)
\(\text{Ta có : }\)
\(a+b+c=259\)
\(a+b=184\)
\(b+c=97\)
\(\Rightarrow\text{ }\left(a+b+c\right)-\left(a+b\right)=c\)
\(\Rightarrow\text{ }259-184=c\)
\(\Rightarrow\text{ }c=75\)
\(\Rightarrow\text{ }b+c=97\)
\(\Rightarrow\text{ }b+75=97\)
\(\Rightarrow\text{ }b=97-75\)
\(\Rightarrow\text{ }b=22\)
\(\Rightarrow\text{ }a+b+c=259\)
\(\Rightarrow\text{ }a+\left(22+75\right)=259\)
\(\Rightarrow\text{ }a+97=259\)
\(\Rightarrow\text{ }a=259-97\)
\(\Rightarrow\text{ }a=162\)
\(\text{Vậy : }\)
\(\Rightarrow\text{ }a=162\)
\(\Rightarrow\text{ }b=22\)
\(\Rightarrow\text{ }c=75\)
