suraj thinks of a number and subtract 5/2 and multiple the rebuilt by8 .the result is 3 time the same number he thought of what is the number​

Answer 1

Step-by-step explanation:

Well

let's assume he thought of a no. X

x-5/2 is the rebuilt

now multiply by 8

(x-5/2)*8=3(the result)

therefore,answer is 23/8

Answer 2

Step-by-step explanation:

let

the number= x

suraj subtracted 5/2 = x -5/2

and rebuilt by multiplying by 8

then

x - 5/2 +8

he got 3 times the same number = 3x

x - 5/2 +8 =3x

x - 20 =3x

if x - 20 goes RHS side

3x - x + 20 =0

2x = -20

x = -20 /2

x = -10

there fore ,

the number is -10

may be I think it is right

if wrong sorry
