Question

231 - ( x - 6 ) = 1339 : 13

Answer 1

231 - ( x - 6 ) = 1339 : 13

231 - x + 6 = 103

231 - x = 103 - 6

231 - x = 97

         x = 231 - 97 

         x = 134

Answer 2

231-(x-6)=1339:13

=>231-(x-6)=103

=>x-6=231-103

=>x-6=128

=>x=128+6

=>x=134

Answer 3

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

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

\(\Leftrightarrow237-x=103\)

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

\(-x=-134\)

\(\Leftrightarrow x=134\)

Answer 4

231 - ( x - 6 ) = 1339 : 13

231 - ( x - 6 ) = 103

x - 6 = 231 - 103

x - 6 = 128

x = 128 + 6

x = 134

Vậy x = 134
