Question

If (2a+3)/5 = a/2, then a+3 = ?

Answer 1

The study guide gave me the answer, I just don't understand how they got 9. I am still a little confused.

Answer 2

\[\frac{(2a+3)}{5} = \frac{a}{2} \rightarrow 2(2a+3) = 5a \rightarrow 4a+6=5a\]
i.e.6=5a -4a
i.e. 6=a
or a=6
since we need to find a+3
therefore a+3= 6+3=9
i.e. a+3=9 which is the required ans.
