You can put this solution on YOUR website!
You want all TERMS of a on one side (usually), and only constants on the other side. Understand that -5%2Fa is not really a term of a.

Starting from your given equation, you need to use:
Multiplicative Inverse of a;
Additive Inverse of a;
Additive Inverse of -5;
You should have a quadratic equation. Can you factor it? If yes, then, use the Multiplication Property of Zero.

Those are not the actual steps; they are just the reasons for them.

Sometimes you want all numbers on one side, and zero on the other side.
