To solve the equation $$ a - 15 = 4a - 3 $$ for $$ a $$, follow these steps:

1. **Subtract $$ a $$ from both sides** to bring all terms containing $$ a $$ to one side of the equation:

$$
   a - 15 - a = 4a - 3 - a
   $$
   
   Simplifying both sides:

$$
   -15 = 3a - 3
   $$

2. **Add 3 to both sides** to isolate the term with $$ a $$:

$$
   -15 + 3 = 3a - 3 + 3
   $$
   
   Simplifying both sides:

$$
   -12 = 3a
   $$

3. **Divide both sides by 3** to solve for $$ a $$:

$$
   \frac{-12}{3} = \frac{3a}{3}
   $$
   
   Simplifying:

$$
   -4 = a
   $$

So, the solution is:

$$
a = -4
$$
$$ a = -4 $$
