#### Explanation:

First, use the distributive property on the parentheses and combine like terms

Then, subtract **3a** from both sides

Finally, solve for **a**

Now that we know what **a** is, we can substitute for **a** in the original equation

**(correct)**

We can now conclude that **a** is equal to **15**
