a/ 1818 : (6x - 37) = 18
6x- 37 = 101
6x = 138
x= 23
b/ (x : 23 + 45) . 67 = 8911
x : 23 + 45 = 133
x: 23 = 88
x = 2024
a/ 1818 : ( 6x - 37 ) = 18
6x - 37 = 1818 : 18
6x - 37 = 101
6x = 101 + 37
6x = 138
x = 138 : 6
x = 23
b/ ( 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
\(a,1818:\left(6x-37\right)=18\)
\(\Leftrightarrow6x-37=101\)
\(\Leftrightarrow6x=138\)
\(\Leftrightarrow x=23\)
Vây x = 23
b, \(\left(\frac{x}{23}+45\right).67=8911\)
\(\Leftrightarrow\frac{x}{23}+45=133\)
\(\Leftrightarrow\frac{x}{23}=88\)
\(\Leftrightarrow x=88.23=2024\)
Vậy x = 2024.
a) 1818:(6×x-37)=18
6×x-37=1818:18
6×x-37=101
6×x = 101+37
6×x= 138
x=138:6
x=23
