Question

I am thinking of a number. When you add the
number to itself then multiply by 3 you get 36.
What is the number?

Answer 1

Hi there! :)

Answer:

$\huge\boxed{6}$

Let "x" represent a number.

Adding the number to itself gives us x + x, or 2x.

Multiplying by 3 gets 36, therefore:

36 = 3 · 2x

Simplify:

36 = 6x

Divide both sides by 6:

36/6 = 6x/6

x = 6.
