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!

3600:[(5x+335):x]=50
=>(5x+335):x=3600:50
(5x+335):x=72
=>5x.1:x+335.1:x=72
=>=5+335:x=72
=>335:x=67
x=335:67
x=5
3600:[(5x+335):x]=50
(5x+335):x=3600:50
(5x+335):x=72
5x+335=72x
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
d)3600/[(5x+335)/x]=50
(5x+355)/x=3600/50
5x+355=72x
72x-5x=355
67x=355
x=355/67
\(3600:\left[\left(5x+335\right):x\right]=50\)
\(\left[\left(5x+335\right):x\right]=3600:50\)
\(\left[\left(5x+335\right):x\right]=72\)
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=72
=>5x+335=72.x
=>72x-5x=335
=>67x=335
=>x=5
vậy x=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
