Question

-10 ÷(? +1)-6 =30 ; what is the answer

Answer 1

Let the question will be replaced with x ,

ATQ,

[ - 10 / ( x + 1 ) ] - 6 = 30

- 10 / ( x + 1 ) = 30 + 6

- 10 / ( x + 1 ) =36

- 10 = 36( x + 1 )

- 10 = 36x + 36

-10 - 36 = 36x

- 46 = 36x

-46 / 36 = x

- 23 / 18 = x

Hence, Question will be replaced by -23 / 18

Answer 2

Hey !!

Let ? = Y




Therefore,



-10 / ( Y + 1 ) - 6 = 30




-10 / ( Y + 1 ) = 30 + 6




-10 = 36 ( Y + 1 )




36Y + 36 = -10


36Y = -10 - 36



36Y = -46


Y = -46/36 = -23/18


Hence,


? = -23/18
