cảm ơn Hữu Nghĩa nhé , anh họ tôi

Ai trả lời đúng mình sẽ k cho 😻🤓

460+340=x+\(\frac{157}{5}\)+30

460+340=x+\(\left(\frac{157}{5}+30\right)\)

800=x+61,4

x=800-61,4

x=\(\frac{3693}{5}\)=738,6

\(460+85\) x \(4=\frac{x+175}{5}+30\)

 \(460+340=\frac{x+175}{5}+30\)

\(800=\frac{x+175}{5}+30\\ \frac{x+175}{5}=800-30\\ \frac{x+175}{5}=770\)

\(x+175=770\) x \(5\)

\(x+175=3850\\ x=3850-175\\ x=3675\)

460 - 80 x 4 = ( x + 200) : 4
460 - 340 = (x + 200) : 4
120 = ( x + 200) : 4
x + 200 = 120 x 4
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

800              = x + ( 200 x 4 )

800              = x + 800

x                 = 800 - 800

x                 = 0

 \(460+85.4=\left(x+200\right).4\)

 \(460+340=\left(x+200\right).4\)

 \(800=\left(x+200\right).4\)

\(x+200=3200\)

\(x=3200-200\)

\(x=3000\)

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

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

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

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

\(\Rightarrow x+200=885.4\)

\(\Rightarrow x+200=3540\)

\(\Rightarrow x=3540-200\)

\(\Rightarrow x=3340\)

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

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

Tìm x biết:

a) 285 x x + 155 x x=400

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

5^x = 125

x = 3

460 + 340 = (x + 200) : 4

800 = (x + 200) : 4

x + 200 = 800 : 4

x + 200 = 200

x = 200 - 200

x = 0

Hội con 🐄 chúc bạn học tốt!!!

460 + 340 = (x+200):4

8--=(x+200):4

x+200=800:4

x+200=200

x=200-200

x=0

5^x=125

x=3

\(460+85.4=\left(x+200\right):4\)

\(\Rightarrow\left(x+200\right):4=460+85.4\)

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

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

\(\Rightarrow\left(x+200\right)=800.4\)

\(\Rightarrow x+200=3200\)

                  \(x=3200-200\)

                    \(x=3000\)

          Vậy \(x=3000\)

b) \(5^x=125\)

\(\Rightarrow5^x=5^3\)

Cơ số giống nhau suy ra số mũ giống nhau 

\(\Rightarrow x=3\)

Vậy \(x=3\)

Chúc bạn học tốt !!!
