Question

(x+2,7)x3,6=26,1 

giup minh nha thanks you

Answer 1

( x + 2,7 ) x 3,6 = 26,1 

=> x + 2,7 = 26,1 : 3,6

=> x + 2,7 = 7,25

=> x         = 7,25 - 2,7

=> x         = 4,55

Answer 2

  \(\left(x+2,7\right).3,6=26,1\)

\(\Rightarrow x+2,7=26,1:3,6\)

\(\Rightarrow x+2,7=7,25\)

\(\Rightarrow x=7,25-2,7\)

\(\Rightarrow x=4,55\)

Vậy x = 4,55

Answer 3

Dấu \("."\) là dấu nhân 

\(\left(x+2,7\right).3,6=26,1\)

\(\left(x+2,7\right)=26,1:3,6\)

\(x+2,7=7,25\)

\(x=7,25-2,7\)

\(x=4,55\)

Vậy \(x=4,55\)

Chúc bạn học tốt !!!!
