3636 : 36 = 101
101 + 91 = 192
192 : 12 = 16 vậy x = 16 tick đúng nha Nguyễn Đan Khanh
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
a) \(\left(x+74\right)-310=200\)
\(x+74=200+310\)
\(x+74=510\)
\(x=510-74\)
\(x=436\)
b) \(3636:\left(12\cdot x-91\right)=36\)
\(12\cdot x-91=3636:36\)
\(12\cdot x-91=101\)
\(12\cdot x=101+91\)
\(12\cdot x=192\)
\(x=192:12\)
\(x=16\)
Vậy ....
a/ => x - 2 = -25 => x = -23
b/ => 15 - x = -4 => x = 19
c/ => 12x - 91 = 1/101
=> 12x = 9192/101
=> x = 766/101
a 3.x-2.x=84-24
x=60
b 12x-91=3636:36
12x-91=101
12x=101+91
12x=192
x=192:12=16
a) ( x + 74 ) - 318 = 2015
=> x + 74 = 2015 + 318
=> x + 74 = 2333
=> x = 2333 - 74
=> x = 2259
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 + 45 = 133
=> x : 23 = 133 - 45
=> x : 23 = 88
=> x = 88 . 23
=> x = 2024
Tìm x, biết :
a) ( x + 74) - 318 = 2015
(x + 74) = 2015 + 318
(x + 74) = 2333
x = 2333 - 742
x = 2259
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 + 45) = 133
x : 23 = 133 - 45
x : 23 = 88
x = 88 . 23
x = 2024
. là nhân nha
a: \(3636:\left(12\cdot x-91\right)=36\)
=>\(12x-91=\frac{3636}{36}=101\)
=>12x=91+101=192
=>\(x=\frac{192}{12}=16\)
b: \(446+2\cdot\left(125-x\right)=546\)
=>\(2\left(125-x\right)=546-446=100\)
=>125-x=50
=>x=125-50=75
c: \(\left(x-36\right):18=10+2\)
=>\(\left(x-36\right):18=12\)
=>\(x-36=18\cdot12=216\)
=>x=216+36=252
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
\(3636:\left(12x-91\right)=36\)
\(=>12x-91=101\)
\(=>12x=192\)
\(=>x=96\)
3636:(12.x-91)=36
12.x-91=3636:36=101
