# How do you solve x – 14 = 20 ?

Mar 25, 2018

$x = 34$

#### 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)

$x - 14 = 20$

$x - 14 + 14 = 20 + 14$

$x = 34$

Solve for $x$.

#### Explanation:

add 14 to both sides to get X by its self

$x - 14 + 14 = 20 + 14$

$x + 0 = 34$

$x = 34$

$x = 34$

#### 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.

$x - 14 = 20 \to x = 20 + 14 \to x = 34$

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.

$x = 34$

#### 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:

$x \cancel{- 14 + 14} = 20 + 14$

$\implies x = 34$

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

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