I'm a sixth grader in a pre algebra class this is confusing lol me

Algebra is my weak spot, but I've done this before.

Okay, as an example,

x - a = a - x

Substitute the numbers,

So if x = 2 and a = 7, we can put them together as

2 - 7 = 7 - 2

The main goal is to simplify each side and then see if they match.

2 - 7 = −5
7 - 2 = 5

You can implement the answers like this:

-5 = 5

-5 and 5 ARE NOT EQUAL TO EACH OTHER. They are not the same number.

So, you would put a slash through the equal sign and say that the statement is false.

If a problem, for example, has an answer that looks like this:

12 = 12

The statement is true and you leave the equal sign alone.

Good luck, fam
