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

x=5 day ban oi

nhe

x chính xác là =5 mình thi rồi

x= 5 nha ban

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

Đề thiếu 1 dấu ngoặc vuông chưa biết đóng ở đâu cả

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

=> 5x + 335 = 72x

=> 335 = 72x - 5x

=> 335 = x.( 72 - 5 )

=> 335 = 67x

=> x = 335 : 67

=> x = 5

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

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

=> 5x + 335 = 72x

=> 5x - 72x = -335

=> -67x = -335

=> x = 5

Vậy x = 5

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

=>5x+335:x=72

=>335:x=72-5

=>335:x=67

=>x=335:67

=>x=5

đúng đó bn
