( \(\frac{x}{23}\) + 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 \(x=2024\)

\((x-17)+52=158\)
\(\Rightarrow x-17=158-52\)
\(\Rightarrow x-17=106\)
\(\Rightarrow x=106-17\)
\(\Rightarrow x=89\)
( 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

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

a/ \(3636\div\left(12x-91\right)=36\)
\(12x-91=3636\div36\)

\(12x=192\)
\(x=192\div12\)
\(x=16\)

\(x\div23=133+45\)
\(x\div23=178\)
\(x=178\times23\)
\(x=4094\)
(x : 23 + 45). 67 = 894
=> x : 23 + 45 = 894 : 67
=> x : 23 + 45 = \(\frac{894}{67}\)
=> x : 23 = \(\frac{894}{67}\)+ 45
=> x : 23 = \(\frac{3909}{67}\)
=> x = \(\frac{3909}{67}.23\)
=> x = \(\frac{89907}{67}\)
Vậy: x có giá trị = \(\frac{89907}{67}\)
Đề sai rồi bạn ơi! 894 không chia hết cho 67
