Since they are like terms, 5a*3a=15a. Find out what "a" is equal to and multiply it by 15. Then, and only then, will you get your answer.
two like terms will always have the same alphabet for example: 3a and 5a are like but 3a and 5b are not
(5a+8) - (2a+4) =3a +4 To do this, simply subtract like terms. 5a-2a=3a and 8-4=4

2a + 3a = 5a

The given expression can be simplified to: 3b-a
6b+5a-4b+3a= ? Rearrange it as 5a+3a+6b-4b = 8a+2b
5a + 4b - 3a =(5a - 3a) + 4b =2a + 4b =2 (a + 2b)
2a + 5a + 3a = 10a
-8a + 3a = (-8 + 3)a = (5)a = 5a
2a - 5a = -3a
If 3a+5=5a+3, then: 3a+5 - 3a = 5a+3 - 3a 5=2a+3 5 - 3=2a+3 - 3 2=2a a=1
a + 3a + 5a = 180 9a =180 a = 20
