\(3600:\left[\left(5x+335\right):x\right]=50\)
\(\left[\left(5x+335\right):x\right]=3600:50\)
\(\left[\left(5x+335\right):x\right]=72\)
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
