3636 : 36 =101
101 + 91 = 192
192 : 12 = 16
vậy x bằng 16 nha bn!
k cho mk nha!!
3636: (12x-91) =36
12x-91 =3636:36
12x-91 =101
12x = 101: -91
12x = \(-\frac{101}{91}\)
x = \(-\frac{101}{91}:12\)
x= \(-\frac{101}{1092}\)
\(\Rightarrow12x-91=\dfrac{3636}{36}=101\\ \Rightarrow x=16\)
3636 : (12x - 91) = 36
12x - 91 = 3636 : 36
12x - 91 = 101
12x = 101 + 91
12x = 200
x = 192 : 12 = 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
3636:(12x-91) =36
12x - 91 = 3636 :36
12x-91 =1212
12x = 1212 - 91
12x = 1121
=> x = 1121 : 12
x = \(\frac{1121}{12}\)
nếu đúng thì tick cho mình nha,Vũ Quỳnh Hương
minh lam lun ko ghi lai de
a, 12x-91=3636:36
12x=101+91
x= 192:12
x=16
b, x:23+45=8911:67
x:23=133-45
x=88.23
x=2024
k mk nha
câu 1:
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
câu 2:
(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
\(71-\left(33+x\right)=26\)
<=> \(71-33-x=26\)
<=> \(38-x=26\)
<=> \(x=38-26=12\)
\(3636:\left(12x-91\right)=36\)
<=> \(12x-91=101\)
<=> \(12x=192\)
<=> \(x=16\)
\(\left(x-15\right)-218=0\)

1) 71 - ( 33 + x ) = 26
<=> 33 + x = 71 - 26
<=> 33 + x = 45
<=> x = 12
2) 3636 : ( 12x - 91 ) = 36
<=> 12x - 91 = 101
<=> 12x = 192
<=> x = 16
3) ( x - 15 ) - 218 = 0
<=> x - 15 = 218
<=> x = 218 + 15
<=> x = 233
4) 45 + ( x - 6 ) .3 = 81
<=> 45 + ( x - 6 ) = 27
<=> x - 6 = -18
<=> x = -12
5) 124x - 4x - 70x = 150
<=> 5x = 150
<=> x = 150 : 50
<=> x = 3
