Question

How do you solve `p- 13= 20`?

Answer 1

`p=33`

Explanation:

To get this answer, you have to follow the "golden rule" of algebra, which is: whatever you do to one side, you must do to the other.

We have to isolate the variable, in this case, is `p`. To do that, you can add `13` to both sides of the equation, because the operation sign in front of `13` is negative. Now, the equation becomes

`p+0=33`

and if you take the `0` out, (because it is understood), you will get the answer

`p=33`

Answer 2

In order to solve this combine like terms

Explanation:

Step 1:

Combine your like terms

`p - 13 = 20`

In order to combine like terms, you do the opposite of whats given.

So, `13 + 20 = 33`

Step 2:

Bring your P down

`P = 33`

Your answer is `P = 33`
