Question

Answer 1

Ok thought of a number.

Let that the number be x.

Multiply with 6.

We get 6x.

Add 3

So 6x+3.

Subtract z from the result.

Now I have to tell my secret

I thought the number as 2.

So

6x+3

=6*2+3

=12+3

=15

15-z is the result.

Well it depends on what numbers you choose.

If you choose anything like a.

6a+3-z will be the answer.

Hope it helps.
