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

Tìm x biết:

a) 285 x x + 155 x x=400

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

<=>460+360=4x+800

<=>800=4x+800

<=>x=0

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

460 + 340     = ( x + 200 ) x 4

800              = ( x + 200 ) x 4

800              = x + ( 200 x 4 )

800              = x + 800

x                 = 800 - 800

x                 = 0

 \(460+85.4=\left(x+200\right).4\)

 \(460+340=\left(x+200\right).4\)

 \(800=\left(x+200\right).4\)

\(x+200=3200\)

\(x=3200-200\)

\(x=3000\)

\(\Rightarrow\)\(x=3000\)

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 !! ==" 

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

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

Không viết lại đề nha!

460 + 340 = (x + 200) : 4

800 = (x + 200) : 4

x + 200 = 800 : 4 = 200

x = 200 - 200 = 0

Hội con 🐄 chúc bạn học tốt!!!

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

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

#) Trả lời :

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

460 + 340 = ( x + 200 ) : 4

800 = ( x + 200 ) :4

800  x 4 = x + 200

3200 = x + 200

3200 - 200 = x

3000 = x

Hk tốt nha bn :3

                 460-85*4=(x+200) :4

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

a.460+340=(x-200)x4

800=(x-200)x4

800:4=x-200

200=x-200

x=200+200

x=400

b.x=53

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

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

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

\(\Rightarrow x+200=885.4\)

\(\Rightarrow x+200=3540\)

\(\Rightarrow x=3540-200\)

\(\Rightarrow x=3340\)

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 + 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
