Question

I am xyears old and my brother is 3years older .how old was my brother last year.​

Answer 1

`\Huge \boxed{\text{Brother's age = x - 2}}`

Explanation:

Let's start by calling your age
`x`. We know that your brother is 3 years older than you, so we can represent his age as
`x+ 3`.

Now, we want to figure out how old your brother was last year. To do this, we need to subtract 1 from his current age. So, we get:

`(x + 3) - 1`

We can simplify this by subtracting 1 from 3, which gives us 2. So, we can rewrite the equation as:

`x + 2`

This tells us that your brother was
`\bold{x + 2}` years old last year.

Example

To give you an example, let's say you're 15 years old. Then, your brother is 18 (because 15 + 3= 18).

Last year, your brother's age was:

18 - 1 = 17

So, when you were 15 and your brother was 18, your brother was 17 years old last year.
