Question

How do you solve `x – 14 = 20`?

Answer 1

`x = 34`

Explanation:

You want `x` to be alone on one side, so you add `14`:
(If you can't do it in your head, you write `+ 14` on both sides)

`x - 14 = 20`

`x - 14 + 14 = 20 + 14`

`x = 34`

Answer 2

Solve for `x`.

Explanation:

add 14 to both sides to get X by its self

`x-14 +14 = 20 +14`

`x + 0 = 34`

`x=34`

Answer 3

`x=34`

Explanation:

As with any given letter in algebra, we are trying to solve to find the value of the letter.

Given:

`x-14=20`

We want to find `x` on its own, and we do the opposite to the operation given.

The opposite to `-14` is to `+14`, remember that these cancel out, and what you do to one side you MUST do to the other.

`x-14=20 -> x=20+14 -> x=34`

We can always check this.

Given:

`x-14=20`

Plugging in the value of `x`

`34-14=20` which is true, therefore we are correct.

Answer 4

`x=34`

Explanation:

We want to solve for `x`, and at the moment, `14` is being subtracted from it. To isolate it, we must do the inverse operation.

This would be adding `14` to both sides. We get:

`xcancel(-14+14)=20+14`

`=>x=34`

To check our answer, we can plug in `34` for `x`. We get:

`34-14`, which is indeed equal to `20`.
