Get rid of the fractions by multiplying by 2 on both sides to get
6a -16 = a + 4
Then subtract a from both sides to get
5a -16 = 4
Add 16 to both sides to get
5a = 20
Divide each side by 5 to get
a=4

3a-a/2 = 10
5a/2 = 10
5a = 20
a = 4

3a - 8 = (a + 4)/2
2(3a - 8 ) = a + 4
6a -16= a + 4
5a = 20
a =4

ok first you birng over the 2 by subtracting 2 on both sides
3a-10=a/2
then you multiply everything by 2
6a-20=a
then you birng over the 6a by subtraction
-20=-5a
Lastly you divide by -5
4=a
hope that helped! :)
