Question

Combine like terms 2/3a+4/3b-4/3a

A) 4/3b-2/3a
B)2/3ab
C)2/3a
D)4/3b-8/9a

Answer 1

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

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

Answer 2

A)

Explanation:

`(2)/(3)-(4)/(3)  =-(2)/(3)`

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
