Question

biết 8.y+y.17=15675

Answer 1

 8.y+y.17= 15675

 (8+17).y=15675

25.y=15675

y=15675:25

y=627

Answer 2

=> 25y = 15675

=> y = 15675 : 25

=> y = 627

Vậy...

Answer 3

8y + 17y = 15675

<=> y( 8 +17 ) = 15675

<=> 25y = 15675

<=> y = 15675 : 25 = 627

Answer 4

8y + y.17 = 15675

y.(8  + 17) = 15675

y.25 = 15675

y = 627
