Question

Simplify this equation -8a-5a

Answer 1

-13a

Explanation:

These two numbers are already like terms, so you can subtract it easily.

First, don't look at the a.

-8-5= -13 because if something is negative and gets subtracted, that means it'll still be negative.

Now that we now it equals -13, we can add the variable a back onto the answer. We get -13a.

Answer 2

-13a

Explanation:

Since -8 and -5 have like variables, you can subtract them. -8-5 is -13, so the answer is -13a.
