Combine 2a - 3b + 5b - a a) 3ab b) 3a + 2b c) 7a - 4b d) a + 2b explain and show

add like terms

 2a - 3b + 5b - a

= (2a - a)  +  (-3b + 5b)

=     a       +      2b

D) a + 2b

The correct answer is D) a + 2b.

In order to find the answer to this problem, first group the like terms. Start with the a terms.

2a - a = a

Now do the same with the b terms.

-3b + 5b = 2b.

Now that we have each of these answers, we can put them together to form 1 + 2b, which is your final answer.
