Question

420: x + 27 . 11= 325 tìm x

giúp nhé

 

Answer 1

420: x + 27 . 11= 325

420:x+297=325

420:x=28

x=420:28

x=15

Vậy x=15

Answer 2

420: x+ 27. 11= 325

=> 420: x+ 297= 325

=> 420: x= 325- 297

=> 420: x= 28

=> x= 420: 28

=> x= 15

Vậy x= 15

Answer 3

\(420:x+27\cdot11=325\)

\(420:x+297=325\)

\(420:x=325-297\)

\(420:x=28\)

\(x=420:28\)

\(x=15\)

Vậy \(x=15\)
