Add them together: 3a+4a-a = 6a
You need to combine the different parts that contain the variable "a". Just add the coefficients together algebraically.
2b+b-4
It is an expression of two terms as: 4a+12
"a" plus "3a" is equal to 4a. (3a+a=4a). You already have 3 "a's" and then you add another "a."
3a * * * * * Actually, it is 4a.
5x - 8a + 4a - 2x + a = 3x - 3a
4a+5=25 4a=25-5 4a=20 a=20/4 a=5
= 4a2 + 2ab 2b2
2a+6b
11a+7b-(3b-2a)
3a - 2b
7
Add them together: 3a+4a-a = 6a
6a - 8 - 4a - 2 → 6a - 4a - 8 - 2 → 2a - 10
It is -44 + 4a
