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

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

\(231-\left(x-6\right)=1339:13\)
\(231-\left(x-6\right)=103\)
\(x-6=231-103\)
\(x-6=128\)
\(x=134\)
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 - ( x - 6 ) = 1339 : 13
231 - x + 6 = 103
231 - x = 103 - 6
231 - x = 97
x = 231 - 97
x = 134
231-(x-6)=1339:13

Hk tốt !

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

\(x-6=-231-103\)
\(x-6=-334\)
\(x=-334+6\)
\(x=-328\)

231 - ( x - 6) = \(\frac{1339}{3}\)
<=> x - 6 = \(\frac{-646}{3}\)
<=> x = \(\frac{-628}{3}\)
231 - ( x - 6 ) = 1339 / 12
( x - 6 ) = 231 - 1339/12
( x - 6 ) = 1373/12
x = 1373/12 + 6
x = 1445/12
