−5x+8x+5

Answer 1

-5x + 8x + 5

We must combine like terms.

That basically just means that we add anything that has any like variables :)

In this case, our like terms are the variable "x."

So, we must add -5x to 8x

Think of this as if there were no "x" in there.

So, it looks like this : -5 + 8

What's -5 + 8?

It's 3! So, now we just need to add an 'x' after the 3.

So, -5x + 8x = 3x

Since we have no more like terms, our answer is :

3x + 5
