Question

Tìm x : 

7 -  ( 11 + x -13 ) :  \(2\frac{2}{3}\)= 2

Ai giải đúng và đầy đủ thì mk tk cho 3 tk 

Answer 1

(11+x-13):\(2\frac{2}{3}\)=7-2

(11+x-3):\(\frac{8}{3}\)=5

11+x-3 =5 * \(\frac{8}{3}\)

11+x-3=\(\frac{40}{3}\)

x-3=\(\frac{40}{3}\) -11=\(\frac{40}{3}\) -\(\frac{33}{3}\)

x-3=\(\frac{7}{3}\)

x=\(\frac{7}{3}\) +3=\(\frac{7}{3}\)+\(\frac{9}{3}\)

x=\(\frac{16}{3}\)=\(5\frac{1}{3}\)

Answer 2

7 - ( 11 + x - 13 ) = 2 x \(\frac{8}{3}\)

7 - ( 11 + x - 13 ) = \(\frac{16}{3}\)

11 + x - 13 = 7 - \(\frac{16}{3}\)

11 + x - 13 = \(1\frac{2}{3}\)

11 + x = \(1\frac{2}{3}\)+ 13 

11 + x = \(14\frac{2}{3}\)

x = \(14\frac{2}{3}-11\)

x = \(3\frac{2}{3}\)

Vậy x = \(\frac{11}{3}nha\)!!!

Answer 3

11/3 nha
