\(230-\left(x-12\right)=1339:13\)
\(230-\left(x-12\right)=103\)
\(x-12\text{ }=230-103\)
\(x-12\text{ }=127\)
\(x\) \(=127+12\)

231 - (x - 6) = 1339 : 13
=> 231 - (x - 6) = 103
=> x - 6 = 231 - 103
=> x - 6 = 128
=> x = 128 + 6
=> x = 134
Vậy x = 134

\(231-\left(x-6\right)=\frac{1339}{13}\)
\(231-\left(x-6\right)=\frac{1339}{13}=103\)
\(=>231-103=x-6\)
\(=>x-6=128\)
\(=>x=128+6=134\)
\(\Leftrightarrow\)231-x+6=103
\(\Leftrightarrow\)231-x=103-6
\(\Leftrightarrow\)x=231-97
\(\Leftrightarrow\)x=134
