mình kon hỉu đề bn ơi

ở cuối dấu = hay + vậy bạn "="25+73 ý

4965 nhưng mình không chắc lắm 

420 + 65 . 4 = ( x + 175 ) : 5 + 30 

=> ( x + 175 ) : 5 + 30 = 420 + 45 . 4 

=> ( x + 175 ) : 5 + 30 = 600 

=> ( x + 175 ) : 5 = 600 - 30 

=> ( x + 175 ) : 5 = 570 

=> x + 175 = 570 . 5 

=> x + 175 = 2850 

=> x = 2850 - 175 

=> x = 2675

Có:  \(35x+15=890\Rightarrow35x=875\Rightarrow x=25\)

\(1) 420+65.4=(x+175):5+30\)

\(\implies 420+260=(x+175):5+30\)

\(\implies 680=(x+175):5+30\)
