Already explained in https://www.algebra.com/algebra/homework/Linear-equations/Linear-equations.faq.question.1122014.html

You really have %283%2F8%29a-8=13.
%283%2F8%29a=13%2B8
a=%2813%2B8%29%288%2F3%29, which you can compute mentally.


On a calculator, you can press buttons like this:
13 PLUS 8 EQUAL, MULT BY 8, DIV BY 3

or

(13) (+) (8) (=) (X) (8) (DIVIDEDBY) (3)
