=> 12x - 91 = 101

=> 12x = 192

=> x = 16

3636 : 36 =101

101 + 91 = 192

192 : 12 = 16

vậy x bằng 16 nha bn!

k cho mk nha!!

k mk nha

câu 1:

3636:(12*x-91)= 36

3636.(12x-91)=36

12x-91=1/101

12x=9192/101

x=766/101

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

lúc nãy mình nhầm nha

=> x = 192 : 12

=> x = 16

Vậy x = 16 

Sorry nhìu, nãy mình nhầm mình đem chia 2, hjhj

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

3636 : (12x-91) = 36

=> 12x - 91 = 3636 : 36

=> 12x - 91 = 101

=> 12x = 101 + 91

=> 12x = 192

=> x = 192 : 12

Vậy x = 16.
