K cho mk nha bn!
a ) (x+74 ) - 218 = 200 \(\Leftrightarrow\) x+74-218 = 200 \(\Leftrightarrow\) x= 200+218+74 \(\Leftrightarrow\) x= 492 vậy x = 492 b, 3636 : ( 12x -91) =36 \(\Leftrightarrow\)12x-91 = 3636: 36 \(\Leftrightarrow\)12x-91 = 101 \(\Leftrightarrow\) 12x = 101+91 \(\Leftrightarrow\) 12x = 192 \(\Leftrightarrow\) x= 16 vậy x = 16
c, ( x : 3 +45 ) . 67 = 8911 \(\Leftrightarrow\) x : 3 +45 = 8911: 67 \(\Leftrightarrow\) x : 3 = 133 - 45 \(\Leftrightarrow\) x : 3 = 88 \(\Leftrightarrow\) x= 88 . 3 \(\Leftrightarrow\) x=264
vậy x= 264
Tìm X
a ) ( X + 74 ) - 318 = 200 b ) 3636 / ( 12x -91 ) = 36
c) ( X / 23 + 45 ) * 67 =8911
a ) \(\left(x+74\right)-318=200\)

tìm x
a) (x+74)-318=200
b)3636:(12*x-91)=36
c)(x:23+45)*67=8911
giải hộ minh nha gấp lắm
a. (x+74)-318=200
=>x+74=200+318
x+74=518
x =518-74
x =444
b. 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
c. (x:23+45).67=8911
=>x:23+45=8911:67

x:23 =133-45
x:23 =88
x =88.23
x =2024
318-74=244
200+318=518
mình chỉ biết giải đến đấy thôi đừng giận mình nhé
3636:(12x -91)=36
( x:23+45 ) ×67= 8911
a/ \(3636\div\left(12x-91\right)=36\)
\(12x-91=3636\div36\)
\(12x-91=101\)
\(12x=101+91\)
\(12x=192\)
\(x=192\div12\)
\(x=16\)
b/ \(\left(x\div23+45\right)\times67=8911\)
\(x\div23+45=8911\div67\)
\(x\div23+45=133\)
\(x\div23=133+45\)
\(x\div23=178\)
