 \(460+85.4=\left(x+200\right).4\)

 \(460+340=\left(x+200\right).4\)

 \(800=\left(x+200\right).4\)

\(x+200=3200\)

\(x=3200-200\)

\(x=3000\)

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

Ta có: 460+85,4=(x-200):4

suy ra 460+340=(x-200):4

suy ra 800=9x-200):4

suy ra 800:4=x-200

suy ra x=3200+200=3400

3000 bạn nhé

ta có 460+85.4=(x-200):4 

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

<-> 800=(x-200):4

<->800.4=x-200

->x=3200+200=3400

=3000 mới đúng

dễ mà 460 + 85 * 4 = x + 175 : 5 + 30

          460 + 340    = x + 35 + 30

              800         = x + 65

           800 - 65 = x

             735     = x hay x = 735

460+85x4=(x+175):5+30

<=>460+340=x.1/5+175.1/5+30

<=>800=1/5x+35+30

<=>735=1/5.x

<=>x=3675

Chúc bạn học tốt ^_^

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+85x4=x+175:5+30

460+340=x+35+30

800=x+65

800-65=x

735=x hay x = 135

460 + 85.4 = ( x + 200 ) : 4 

460 + 340 = ( x + 200 ) : 4 

800 = ( x + 200 ) : 4 

x + 200 = 3200

=> x = 3000

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

460 + 340 = (X + 200 ) : 4

     800      = ( X + 200 ) : 4

     X + 200 = 3200

     X           = 3200 - 200

     X            = 3000
