Answer:

A)

Step-by-step explanation:

[tex]\frac{2}{3}-\frac{4}{3} =-\frac{2}{3}[/tex]

You cannot add a variable that is not the same to another variable. Example:

You can add a+a=2a

You can't add b+a because it is not the same variable

Answer:

It's technically A, but A is also wrong in a way, you should put it in alphabetical order but either way A is correct

Step-by-step explanation:

Leave the b alone because there are no other like terms.

But there are like terms for a so just combine them.

So look at the first a term, it is 2/3a

The second like term is -4/3a

MAKE SURE TO INCLUDE THE NEGATIVE

They are the same denominator which makes it easier.

So just do 2/3a-4/3a

You get -2/3a

Now combine the a and b together

-2/3a+4/3b
