Since there is fraction involved, let’s see if we can remove that first.
7a/5 - 2a/5 can be written together as (7a-2a)/5.
Following that, you can solve the left side.
(7a-2a)/5=16
5a/5=16
a=16
Sorry that I have to use my phone to express the fractions. I do not have paper with me.
When algebra is involved, the main goal is to always isolate the algebra on the left. And everything else on the right. By manipulating the equation.

Thank you. I completely understand the explanation for the question
You are welcome, just remember it won’t be this straightforward all the time.
Sometimes the question would ask you to solve
7a-2a=16 instead.
The answer would then be
7a-2a=16
5a=16
a=16/5
