Question

A number increased by 6 equals 20?

Answer 1

See a solution process below:

Explanation:

Let's call "A number": `n`

"increased by" means to have it added to. So, we can write:

`n +`

It is increased by "6" so can continue to write:

`n + 6`

And, it "equals 20" so can complete this as:

`n + 6 = 20`

If we want to solve this we can subtract `color(red)(6)` from each side of the equation to solve for `n` while keeping the equation balanced:

`n + 6 - color(red)(6) = 20 - color(red)(6)`

`n + 0 = 14`

`n = 14`

Answer 2

`14`

Explanation:

Let the number be `x`. Then, `x` is increased by `6`. So

`x+6=20`

`=>x+6-6=20-6`

`=>x=14`
