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:(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

12.x=101+91=192

x=192:12

x=16

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

(12.x-91)=3636:36

12.x-91=101

12.x=101+91

12.x=192

x=192:12

x=16

x=16

3636 - ( 12x - 91 ) = 36

=> 12x - 91 = 3636 - 36

=> 12x - 91 = 3600

=> 12x = 3600 + 91

=> 12x = 3691

=> x = 3691 : 12

=> x = \(\frac{3691}{12}\)

3636-12x+91=36

3727-12x=36

12x=3691

x=\(\frac{3691}{12}\)

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 ....

( x+74)-310=200

x+74=200+310

x+74=510

x=510-74

x=436

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

(x+74)-310=200

 x+74          = 200 + 310= 510

 x                 =510 - 74

 x                 =436

mình làm 1 bài thôi nha

k cho mình nha bạn!!!^_<     

3636 : ( 12 x y - 91 ) = 36

12 x y-91=3636:36=101

12 x y=101+91=192

=>y=192:12=16

3636:(12xy-91)=36

12 x y-91=3636:36

12 x y -91=101

12 x y=101-91

12 x y=10

y=12:10

y=1,2

Ta có : 3636 : 36 = 12 x y - 91

hay 12 x y - 91 = 101

12 x y = 101 + 91

12 x y = 192 

y = 192 : 12 

y = 16

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. = 60

b. = 16

3x + 24 = 2x + 84

=> x     = 84 - 24 

      x    = 60

3636 : ( 12x - 91 ) = 36

             12x - 91   = 101

              12x         = 101 + 91

               12x         = 192

                   x         = 16
