( \(\frac{x}{23}\) + 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 - 36 : 18 = 12
x - 2 = 12
x = 12 + 2
x = 14
(x : 23 + 45) . 67 = 8911
x : 23 + 45 = 8911 : 67
x : 23 + 45 = 133

\((x-17)+52=158\)
\(\Rightarrow x-17=158-52\)
\(\Rightarrow x-17=106\)
\(\Rightarrow x=106-17\)
\(\Rightarrow x=89\)
( x- 17 ) + 52 = 158
x - 17 = 158 - 52
x - 17 = 106
x = 106 + 7
x = 113
Vậy x = 113
( x : 23 + 45 ) : 67 = 8911

minh lam lun ko ghi lai de
a, 12x-91=3636:36
12x=101+91
x= 192:12
x=16
b, x:23+45=8911:67
x:23=133-45
x=88.23
x=2024
k mk nha
câu 1:
3636:(12*x-91)= 36
12*x-91=3636:36
12*x-91=101
12*x =101 + 91
12*x =192
x =192 : 12
x =16
câu 2:
(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
(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
