\(231-\left(x-6\right)=1339:13\)
\(231-\left(x-6\right)=103\)
\(x-6=231-103\)
\(x-6=128\)
\(x=134\)
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 :
\(231-\left(x-6\right)=1339\div13\)
\(\Leftrightarrow231-\left(x-6\right)=103\)
\(\Leftrightarrow x-6=128\)
\(\Leftrightarrow x=134\)
TL:
\(231-\left(x-6\right)=1339:13\)
\(231-x+6=103\)
\(237-x=103\)
\(x=134\)
Vậy x=134
\(231-\left(x-6\right)=1339:13\)
\(\Rightarrow231-x-6=103\)
\(\Rightarrow225-x=103\)
\(\Rightarrow-x=103-225=-122\)
\(\Rightarrow x=122+\)
