Question

a) (x:23+45).67=8911

Answer 1

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

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

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

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

\(\Rightarrow x:23=88\)

\(\Rightarrow x=23.88\)

\(\Rightarrow x=2024\)

Vậy \(x=2024\)

Answer 2

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

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

\(x:23=133-34\)

\(x:23=99\)

\(\Rightarrow x=99\cdot23\)

\(\Rightarrow x=2277\)

Answer 3

(x:23+45).67=8911

       x:23+45=133

Answer 5

Giúp mình câu hỏi này

b)2448:[119-(x-6)]=24

Answer 6

b,2448:[119-(x-6)]=24

2448:(119-x+6)=24

2448:(125-x)=24

125-x=102

x=23

Vậy x=23

Answer 7

=> (X :23+ 45) = 8911 : 67

     (X :23+ 45) =  133

                X:23 = 133 -45 = 88

 =>   X= 88 .23 = 2024

VẬY X= 2024
