Question

If 1 is added to a number and the sum is tripled, the result is 5 more than the number. Find the number

Answer 1

Answer;

`n=1`

Explanation;

Here, we want to get a number

Since the number is not known at the moment, we can start by identifying the number with an a;phabet

Let us call this n

If 1 is added to the number

mathematical representation;

`1+n`

And the sum is tripled;

`3(1+n)`

The result is 5 more than the number

5 more than the number is simply;

`5+n`

So, we equate this to what we had initially as follows;

`5+n=3(1+n)`

We can now solve this equation for n

`\begin{gathered} 5+n=3+3n \\ 5-3=3n-n \\ 2n=2 \\ n=(2)/(2) \\ n=1 \end{gathered}`
