Question

 

tìm X

22/7 : (11 - X ) + 2/3 = 7/5

mong các bạn giúp mik

 

Answer 1

\(\frac{22}{7}:\left(11-x\right)+\frac{2}{3}=\frac{7}{5}\)

\(\frac{22}{7}:\left(11-x\right)=\frac{11}{15}\)

\(11-x=\frac{30}{7}\)

\(x=\frac{47}{7}\)

Vậy \(x=\frac{47}{7}\)

Answer 2

\(\frac{22}{7}\div\left(11-x\right)+\frac{2}{3}=\frac{7}{5}\)

\(\Leftrightarrow\frac{2}{7}-\frac{22}{7x}+\frac{2}{3}=\frac{7}{5}\)

\(\Rightarrow\frac{30x}{105x}+\frac{330}{105x}+\frac{70x}{105x}=\frac{147}{105x}\)

\(\Rightarrow100x+330=147\)

\(\Rightarrow100x=-153\)

\(\Rightarrow x=-1,53\)

Answer 3

#)Giải :

         22/7 : ( 11 - X ) + 2/3 = 7/5

         22/7 : ( 11 - X )         = 7/5 - 2/3

         22/7 : ( 11 - X )         = 11/15

                    11 - X           = 22/7 : 11/15

                    11 - X           = 30/7

                          X            = 11 - 30/7

                          X            = 47/7

Answer 4

\(\frac{22}{7}:\left(11-x\right)+\frac{2}{3}=\frac{7}{5}\)

\(\frac{22}{7}:\left(11-x\right)=\frac{7}{5}-\frac{2}{3}\)

\(\frac{22}{7}:\left(11-x\right)=\frac{11}{15}\)

\(11-x=\frac{22}{7}:\frac{11}{15}\)

\(11-x=\frac{30}{7}\)

\(x=11-\frac{30}{7}\)

\(x=\frac{47}{7}\)

Answer 5

<=> \(\frac{22}{7}:\left(11-x\right)=\frac{7}{5}-\frac{2}{3}=\frac{11}{15}\)

<=>\(\left(11-x\right)=\frac{22}{7}:\frac{11}{15}=\frac{30}{7}\)

<=>\(x=11-\frac{30}{7}=\frac{77-30}{7}=\frac{47}{7}\)
