Question

I think of a number, double it, then Add 15

Answer 1

Let the number be x. Here x acts as any no u think of..right??

step 1: 2x

step 2: 2x+6

step 3: (2x+6)/2

step 4: (2x+6)/2 - x = (x+3) - x = 3 (cancelling 2 in (2x+6)/2,we get x+3 ..dnt get confused :D )

That's y d ans s always 3. :) :)

Stay blessed!!
