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

#) 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

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

<=>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

\(x+200=3200\)

\(x=3200-200\)

\(x=3000\)

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

=> 460 + 340 = (x + 200) : 4

=> x = 3000

1)\(\left(x-280\right):35=56.5\)

\(\left(x-280\right):35=280\)

\(x-280=280.35\)

\(x-280=9800\)

\(x=9800+280\)

\(x=10080\)

2) \(\left(x-128+20\right):192=0\)

\(\Rightarrow x-148=0\)

\(\Rightarrow x=0+148\)

\(\Rightarrow x=148\)

3) \(460+85.4=\left(x+200\right).4\)

\(\Rightarrow\left(x+200\right).4=460+340\)

\(\Rightarrow\left(x+200\right).4=800\)

\(\Rightarrow x+200=800:4=200\)

\(\Rightarrow x=200-200=0\)

4) \(x+5.2-\left(32+16.3:16-15\right)=0\)

\(\Rightarrow x+10-\left(32+3-15\right)=0\)

\(\Rightarrow x+10-20=0\)

\(\Rightarrow x+10=20\)

\(\Rightarrow x=20-10=10\)

nha m.n

Ta có:460+850x4=a+200/4

=>800=a+200/4

=>800x4=a+200

=>3200=a+200

=>a=3200-200=3000

K nhé Nguyễn Phương Chi.

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=(x+200):4

Tìm x biết:

a) 285 x x + 155 x x=400

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