Question

The sum of two number is 11 their diffrence is 5. what is the number?

Answer 1

The answer to this problem is the two numbers `3` and `8`.

Explanation:

The reason for this is because you have two unknowns, or variables, that add up to `11`. Also, we know that one of those values is five less than the other.

So, we can deduce that the equation would be

`x + x - 5 = 11`

Solving this would result in first adding five to both sides so that

`2x = 16`

and dividing both sides by two

`x = 8`

So now we have the first term, and for the second term, you can do one of two things.

The first, understand that `8` is the first term and to find the second would simply be to subtract `5` resulting in the answer `3`.

The second way would be to plug it back into the equation so that

`8 + x = 11`

Subtract `8` from both sides and you get

`x = 3`
