3600:[(5x+335):x]=50

(5x+335):x=3600:50

(5x+335):x=72

5x:x+335:x=72

5+335:x=72

335:x=72-5

335:x=67

\(\Rightarrow\)x=5

Vậy x=5

Đúng thì cho mình nha ^^

(5x+335):x=3600:50

(5x+335):x=72

=>5x+335=72x

=>335=72x-5x=67x

=>x=335:67=5

k cho mk nha

Trả lời:

\(3600:\left[\left(5x+335\right):x\right]=50\)

\(\Leftrightarrow\left(5x+335\right):x=\dfrac{3600}{50}\)

\(\Leftrightarrow\left(5x+335\right):x=72\)

\(\Leftrightarrow\left(5x+335\right).\dfrac{1}{x}=72\)

\(\Leftrightarrow5x.\dfrac{1}{x}+335.\dfrac{1}{x}=72\)

\(\Leftrightarrow5+\dfrac{335}{x}=72\)

\(\Leftrightarrow\dfrac{335}{x}=67\)

\(\Leftrightarrow x=\dfrac{335}{67}\)

\(\Leftrightarrow x=5\)

Vậy \(x=5\).

Chúc bạn học tốt!

x=355/67

3600:[\(\frac{5.x+335}{x}\)] = 50

\(\frac{3600.x}{5.x+335}\)= 50

3600.x = 50.(5.x+335)

3600.x - 250.x = 16750

3350.x = 16750

=> x = 16750 : 3350 = 5

mình cx bí câu này

\(3600:\left[\left(5x+335\right):x\right]=50\)

\(\left[\left(5x+335\right):x\right]=3600:50\)

\(\left[\left(5x+335\right):x\right]=72\)

đến đây thì mik chịu ! Xin lỗi nhé !!!

3600 : [ ( 5x + 335) : x ] = 50

( 5x +335 ) : x = 3600 : 50

( 5x + 335 ) : x = 72

( 5x + 335 ) = 72x

=> 72x-5x = 335

67x = 335

=> x = 5

nick trên làm sai mà kết quả vẫn đúng mới tai chớ hay ,quá hay (đúng là chó ngáp phải ruồi mà)

(5x +335) : x = 72

5x + 335 = 72x

67x = 335

x = 5

     3600 : [(5x + 335) : x] = 50

=> (5x + 335) : x = 3600 : 50

=> (5x + 335) : x = 72

=> 5x : x + 335 : x = 72

=> 5 + 335 : x = 72

=> 335 : x = 72 - 5

=> 335 : x = 67

=> x = 335 : 67

=> x = 5
