Question

A number, double the number, and 16 are added. The result is 61. What is the original number?

Answer 1

`15`

Step-by-step explanation

Let the number be x.

If the number is doubled, it becomes:

`2x`

The number, double the number and 16 are added and the result is 61.

This implies that:

`x+2x+16=61`

Solve for x:

`\begin{gathered} 3x+16=61 \\ 3x=61-16=45 \\ x=(45)/(3) \\ x=15 \end{gathered}`

That is the number.
