(x:3+45)x67-31=8880
(1900 - 2x) : 35 - 32 = 16
=> (1900 - 2x) : 35 = 48
=> 1900 - 2x = 1680
=> 2x = 220
=> x = 110
vậy_
111 + 1818 : (6x - 37) = 129
=> 1818 : (6x - 37) = 18
=> 6x - 37 = 101
=> 6x = 138
=> x = 23
vậy_
(x : 3 + 45) x 67 - 31 = 8880
=> (x : 3 + 45) x 67 = 8911
=> x : 3 + 45 = 133
=> x : 3 + = 88
=>x = 264
vậy_
Tìm x thuộc N :

Mình cần gấp rùi . Giúp mình nha !
Ta có:
\(\left(\frac{x}{23}+45\right).67=8914\)
\(\Leftrightarrow\frac{x}{23}+45=\frac{8914}{67}\)
\(\Leftrightarrow x\div23=\frac{5899}{67}\)
\(\Rightarrow x=\frac{135677}{67}\)
Tìm x, biết:

a ) x = 1 9 + 5 7 = 52 63 b ) x = 2 15 − 3 10 = − 1 6
c ) x = 2 45 − 1 9 = − 1 15 ; d ) x = − 3 7 − 4 5 − − 2 3 = − 59 105
Tìm x, biết:
a) − x − 1 9 = − 2 45
b) − 3 7 − x = 4 5 + − 2 3
a ) x = 2 45 − 1 9 = − 1 15 ; b ) x = − 3 7 − 4 5 − − 2 3 = − 59 105
Tìm số nguyên x, biết :
a, 3x - 75 = 45 + 3 . ( -25 )
b, 2 . ( -7 ) -11 = 6x + 17
c, 37 . ( 29 - 23 ) - 29 . ( 37 - 23 )
d, -4 . /x-3/=-48
\(a,3x-75=45+3.\left(-25\right)\)
\(3x-75=-30\)
\(3x=45\)
\(x=15\)
\(b,2.\left(-7\right)-11=6x+17\)
\(-14-11-17=6x\)
\(-42=6x\)
\(-7=x\Leftrightarrow x=-7\)
\(d,-4.|x-3|=-48\)
\(|x-3|=12\)
\(\Rightarrow\orbr{\begin{cases}x-3=12\\x-3=-12\end{cases}\Rightarrow\orbr{\begin{cases}x=15\\x=-9\end{cases}}}\)
tìm x
a) (x+74)-318+200
b) 3636:(12x91)=36
c) (x:23+45)x67=8911
Tìm x:
a/ 1818 : (6x - 37) = 18
b/ (x : 23 + 45) . 67 = 8911
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.
