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 -> 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.

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.
