\(231-\left(x-6\right)=1339\div13\)

\(231-\left(x-6\right)=103\)

\(x-6=231-103\)

\(x-6=128\)

\(x=128+6\)

\(x=134\)

     231-(x-6)=1339:13

=> 231-(x-6)=103

=> x-6=231-103

=> x-6=128

=> x=128+6

=> x=134

231-(x-6)=1339:13

\(\Rightarrow\)231-(x-6)=103

\(\Rightarrow\)x-6=231-103

\(\Rightarrow\)x-6=128

\(\Rightarrow\)x=128+6

\(\Rightarrow\)x=134.

231 - (x - 6) = 1339/13

231 - x + 6 = 103

(231 + 6) - x = 103

237 - x = 103

x = 237 - 103

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  

#)Giải :

\(231-\left(x-6\right)=1339\div13\)

\(\Leftrightarrow231-\left(x-6\right)=103\)

\(\Leftrightarrow x-6=128\)

\(\Leftrightarrow x=134\)

231 - ( x - 6 ) = 1339 / 12

        ( x - 6 ) = 231 - 1339/12

        ( x - 6 ) = 1373/12

          x        = 1373/12 + 6

          x        = 1445/12

x là 122 nha bn

k mk nha bn

thanks nhju

231 - ( x - 6 ) = 1339 : 13

231 - ( x - 6 ) = 13

           x - 6   = 231 - 13

           x - 6   = 118

            x        = 118 + 6

            x         = 124

\(231-\left(x-6\right)=1339\div13\)

\(231-\left(x-6\right)=103\)

\(x-6=128\)

\(x=128+6\)

\(x=134\)

Đảm bảo đúng mình học rồi!

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

=>231-(x-6)=103

=>x-6=231-103

=>x-6=128

=>x=128+6

=>x=134

Hk tốt !

\(231-\left(x-6\right)=1339\div9\)

\(\Leftrightarrow231-x+6=103\)

\(\Leftrightarrow237-x=103\)

\(\Leftrightarrow-x=103-237\)

\(-x=-134\)

\(\Leftrightarrow x=134\)

_Minh ngụy_

\(231-\left(x-6\right)=\frac{1339}{13}\)

\(231-\left(x-6\right)=\frac{1339}{13}=103\)

\(=>231-103=x-6\)

\(=>x-6=128\)

\(=>x=128+6=134\)

\(\Leftrightarrow\)231-x+6=103

\(\Leftrightarrow\)231-x=103-6

\(\Leftrightarrow\)x=231-97

\(\Leftrightarrow\)x=134

231-x+6=103

134-x=0

x=134
