Simplify the following expression:

6a+2b-2a+3b

4a + 5b

The first term is 6a thus minus 2 from the other a term (which is - 2a)

6 + 2 = 8

The second term is 2b thus add 2 with the other b (which is + 3b.)

2 + 3 = 5

Hope you understand!

6a - 2a = 4a

2b + 3b = 5b

Therefore 4a + 5b is the answer.
