4a+(4a+3).....pls simplify to get answer as a=?

4 a + ( 4a + 3 ) = 8 a + 3

pls tell a=5?

Why do you think a = 5?
You haven't posted an equation. 
is it 8a+3......then a = 38=5

No.
8a means 3 times an unknown number.
8a + 3 means 8 times an unknown number plus 3
The only way we can determine the value of a is in an equation. For instance,
8a + 3 = 83
8a = 83  3
8a = 80
a = 10
