Explanation:

Let the number be `x`.

According to the question

`x+2x=24`

Or, `x=24/3`

Or, `x=8`

Answer 2

Let's have a look.

Explanation:

Firstly, I am doing the second part of your question.

Let the required number be `x`.

So, twice the number is `2x`.

Now given that,

`x+2x=24`.

`:.3x=24`.

`:.x=24/3`.

`:.x=8`.

So, the required number is `8`. (Answer).

Now for the first part of you question, it would be good to ask for a specific type of equation, as there are lots of types of equations & a lot of methods to solve them.

Hope it Helps:).
