Solve inequalities like you would an equation, EXCEPT if you multiply or divide by a negative number, reverse the inequality sign.

Let's look at your problem:

- 20 > 8 + 7a

First subtract 8 from both sides (whatever operation you do to one side you must do to the other side as well):

- 20 - 8 > 8 - 8 + 7a

- 28 > 7a

Divide both sides by 7 to get the variable by itself:

- 28 / 7 > 7a / 7

- 4 > a

I hope this helps.
