( x : 23 + 45 ) . 67 = 8911

=> x : 23 + 45 = 133

=> x : 23 = 88

=> x = 2024

( x : 23 + 45 ) . 67 = 8911

=> x : 23 + 45 = 133

=> x : 23 = 88

=> x = 2024

# ~Hok tốt~

=> x/23 + 45 = 133

=> x/23 = 88

=> x = 23 x 88 = 2024

( \(\frac{x}{23}\) + 45 ) .67 = 8911

 x : 23 + 45       = 8911:67

 x : 23 + 45       = 133

    x : 23            =  133 - 45

       x : 23         =  88

            x           = 88 . 23

            x           = 2024

vậy x = 2024

\(\left(x:23+45\right).67=8911\)

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

\(\Rightarrow x:23+45=133\)

\(\Rightarrow x:23=133-45\)

\(\Rightarrow x:23=88\)

\(\Rightarrow x=23.88\)

\(\Rightarrow x=2024\)

Vậy \(x=2024\)

\(\left(x:23+45\right)\cdot67=8911\)

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

\(x:23=133-34\)

\(x:23=99\)

\(\Rightarrow x=99\cdot23\)

\(\Rightarrow x=2277\)

(x:23+45).67=8911

       x:23+45=133

             x:23=88

                 x=2024

Vậy x=2024

\((x-17)+52=158\)

\(\Rightarrow x-17=158-52\)

\(\Rightarrow x-17=106\)

\(\Rightarrow x=106-17\)

\(\Rightarrow x=89\)

( x- 17 ) + 52 = 158

x - 17 = 158 - 52

x - 17 = 106

x = 106 + 7

x = 113

Vậy x = 113

( x : 23 + 45 ) : 67 = 8911

x : 23 + 45 = 8911 x 67

x : 23 + 45 = 597037

x : 23 = 597037 - 45 

x : 23 = 596992

x = 596992 x 23

x = 13730816

Vậy x = 13730876

(x-17)+52=158

x - 17 = 158 - 52

x - 17 = 106

x= 106+17

x= 123

(x :23 + 45):67=8911

(x : 68 ) : 67 = 8911

x : 68 = 8911 * 67

x : 68 = 597037

x= 597037 x 68

x = 40598516

k mình nhé !!!

(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

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

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

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

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

\(x=88.23\)

\(x=2024\)

   Vậy x = 2024

(x:23+45)*67=8911

x:23+45       =8911:67

x:23+45       =133

x                  =133-(45+23)

x                  =111
