(5x+335):x=72

5x+335=72x

335=67x

=>x=5

5

đúng 100%

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

=>(5x+335):x=3600:50=72

=>5x+335=72x

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

 vậy x=5

= là sao

mình nhầm = là + nha

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

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

5x+335=72.x

335=72x-5x=67x

x=335:67=5

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

\(\frac{5x+335}{x}=72\)

=> 5x + 335 = 72x

=> 335 = 72x-5x

335 = 67x

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

\(\Rightarrow\)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!

355=72x-5x

355=67x

x=355:67

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

Có 3600:( (5x+335) :x )=50 (=) (5x+335) :x =3600:50=72

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

(=)335:x =72-5=67

(=)x =335:67=5 

Vậy x=5

d)3600/[(5x+335)/x]=50

(5x+355)/x=3600/50

5x+355=72x

72x-5x=355

67x=355

x=355/67

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

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

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

=(5x+335):x=72

=5x:x+335:x+72
