Question

Tìm x 

 (x / 23 +45 ) *67 = 8911

Answer 1

(x:23+45)x67=8911

x:23+45=8911:67

x:23+45=133

x:23=133-45

x:23=88

    x=88x23

    x=2024

vậy x=2024

Answer 2

\(\left(\frac{x}{23}+45\right).67=8911\)

\(\frac{x}{23}+45=133\)

\(\frac{x}{23}=133-45\)

\(\frac{x}{23}=88\)

\(x=88.23\)

\(x=2024\)

   Vậy x = 2024

Answer 3

(x:23+45)*67=8911

x:23+45       =8911:67

x:23+45       =133

x                  =133-(45+23)

x                  =111

Answer 4

\(\left(\frac{x}{23}+45\right).67=8911\)

\(\Leftrightarrow\frac{x}{23}+45=8911:67=133\)

\(\Leftrightarrow\frac{x}{23}=133-45=88\)

\(\Leftrightarrow x=88.23\)

\(\Leftrightarrow x=2024\)

Answer 5

câu trả lời của mk sai rồi. lm gấp quá nên ko chú ý 

Answer 6

Bài làm

     \(\left(\frac{x}{23}+45\right).67=8911\)

\(\Rightarrow\frac{x}{23}+45=8911:67\)

\(\Rightarrow\frac{x}{23}+45=133\)

\(\Rightarrow\frac{x}{23}=133-45\)

\(\Rightarrow\frac{x}{23}=88\)

\(\Rightarrow x=23.88\)

\(\Rightarrow x=2024\)

Vậy \(x=2024\)
