K nhé Nguyễn Phương Chi.

460 + 85 x 4 = ( x + 200 ) x 4

460 + 340     = ( x + 200 ) x 4

800              = ( x + 200 ) x 4

\(460+85x4=\left(y+200\right):4\)

\(460+340=\left(y+200\right):4\)

\(800=\left(y+200\right):4\)

\(y+200=800x4\)

\(y+200=3200\)

\(y=3200-200\)

\(y=3000\)

460 + 85 × 4 = y + 200/4

460 + 340 = y + 50

y + 50 = 800

y = 800 - 50

y = 750

Không viết lại đề nha!

460 + 340 = (x + 200) : 4

800 = (x + 200) : 4

x + 200 = 800 : 4 = 200

Hội con 🐄 chúc bạn học tốt!!!

460 + 240 = ( x + 200 ) : 4

700 = ( x + 200 ) : 4

x + 200 : 4 = 700

     x + 200 = 700 x 4

     x + 200 = 2800

               x = 2800 - 200

               x = 2600

460-340=(x+200):4

    1 20  =(x+200  ) :4

  x+200=120*4

 x+200=480

x       =480-200

x      =    280  

   460 - 85 x 4 = (x + 200) : 4

   = 460 - 340 = 120 = (x + 200) : 4

   = (x + 200) : 4 = 120

x = 120 x 4 = 480

x + 200 = 480

x = 480 - 200 

x = 280

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 ^,^

\(3636:\left(12x-91\right)=36\)

\(\Rightarrow12x-91=3636:36\)

\(\Rightarrow12x-91=101\)

\(\Rightarrow12x=101+91\)

\(\Rightarrow12x=192\)

\(\Rightarrow x=16\)

\(460+85\cdot4=\left(x+200\right):4\)

\(\Rightarrow460+340=\left(x+200\right):4\)

\(\Rightarrow800=\left(x+200\right):4\)

\(\Rightarrow x+200=800\cdot4\)

\(\Rightarrow x+200=3200\)

\(\Rightarrow x=3200-200\)

\(\Rightarrow x=3000\)

\(460+85.5=\left(x+200\right):4\)

\(\Rightarrow460+425=\left(x+200\right):4\)

\(\Rightarrow885=\left(x+200\right):4\)

\(\Rightarrow x+200=885.4\)

\(\Rightarrow x+200=3540\)

\(\Rightarrow x=3540-200\)

\(\Rightarrow x=3340\)

Vậy \(x=3340\)

Chúc bạn học tốt !!! 

460 + 85 . 5 = ( x + 200 ) : 4

460 + 425 = ( x + 200 ) : 4

885 = ( x + 200 ) : 4

885 . 4 = x + 200

3540 = x + 200

x = 3540 - 200

x = 3340

=> 460 + 340 = (x + 200) : 4 

=> 800 = (x + 200) : 4

=> x + 200 = 3200

=> x = 3000

460-85x4=(x+200):4

Tìm x biết:

a) 285 x x + 155 x x=400

b) 460 - 85 x 4 = (x + 200) : 4

a.  x - 4300 - (5250 : 1050 : 250) =4240

 x - 4300 - (5 : 250) =4240

 x - 4300 - 0,02 =4240

 x - 4300 = 4240 + 0,02

 x - 4300 =4240,02

x=4240,02+4300

x=854,02

b.  460 + 85 .4 : (x + 200) =4

a.  x - 4300 - (5250 : 1050 : 250) = 4240

=> x - 4300 - 1/50 = 4240

        x - 4300 = 4240 + 1/50 

lk ùi ko lm nữa !! =="
