3636 : (12 . x - 91) = 36
12 . x - 91 = 3636 : 36
12 . x - 91 = 101
12 . x - 91 = 101 + 91
12 . x = 192
x = 192 : 12
x = 16
Vậy x = 16
3636 : (12x - 91) = 36
12x - 91 = 3636 : 36
12x - 91 = 101
12x = 101 + 91
12x = 192
x = 192 : 12
x = 16
Ủng hộ mk nha ☆_★^_-
3636:(12x-91) = 36
=> 12x - 91 = 3636 : 36
=> 12x - 91 = 101
=> 12x = 101 + 91
=> 12x = 192
=> x = 192 : 12
=> x = 96
Vậy x = 96

Câu 1 :\(71+\left(26-3xX\right):5=75\)
\(\left(26-3xX\right):5=75-71\)
\(\left(26-3xX\right):5=4\)
\(26-3xX=4x5\)
\(26-3xX=20\)
\(3xX=26-20\)
\(3xX=6\)
\(X=6:3\)
\(X=2\)
Câu 2 : \(3636:\left(12xX-91\right)=36\)
\(12xX-91=101\)
\(12xX=101+91\)
\(12xX=192\)
\(X=192:12\)
\(X=16\)
3636 : ( 12x - 91 ) = 36
12x - 91 = 3636 :36
12x - 91 = 101
12x = 101 + 91
12x = 192
x = 192 : 12
x = 16
vậy x = 16
460 + 85 . 4 = ( x + 200 ) : 4
460 + 340 = ( x + 200 ) : 4
800 = ( x + 200 ) : 4
( x + 200 ) : 4 = 800
x + 200 = 800 . 4
x + 200 = 3200
x = 3200 - 200
x = 3000
vậy x = 3000
k mk nha bạn
thanks nhìu ^,^
\(3636:\left(12x-91\right)=36\)
\(\Rightarrow12x-91=3636:36\)
\(\Rightarrow12x-91=101\)
\(\Rightarrow12x=101+91\)
\(\Rightarrow12x=192\)
\(\Rightarrow x=16\)
\(460+85\cdot4=\left(x+200\right):4\)
\(\Rightarrow460+340=\left(x+200\right):4\)
\(\Rightarrow800=\left(x+200\right):4\)
\(\Rightarrow x+200=800\cdot4\)
\(\Rightarrow x+200=3200\)
\(\Rightarrow x=3200-200\)
\(\Rightarrow x=3000\)
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 + 45 = 133
x : 23 = 133 - 45
x : 23 = 88
x = 88 . 23
x = 2024
d ) ( 3 . x - 6 ) + 57 = 60
3 . x - 6 = 60 - 57
3 . x - 6 = 3
3 . x = 3 + 6
3 . x = 9
x = 9 : 3
x = 3
\(a)\) \(\left(x+74\right)-318=200\)
\(x+74=518\)
\(x=444\)
Vậy x = 444
\(b)\) \(3636:\left(12x-91\right)=36\)
\(12x-91=101\)
\(12x=192\)
\(x=16\)
Vậy x = 16
\(c)\) \(\left(x:23+45\right)67=8911\)
\(x:23+45=133\)
\(x:23=88\)
\(x=2024\)
Vậy x = 2024
\(d)\left(3x-6\right)+57=60\)
\(3x-6=3\)
\(3x=9\)
\(x=3\)
Vậy x = 3
3636 : 36 = 101
3636 / 36 =101
