Answer 3

To solve the equation $4000 + 5a = 3000 + 3000$, you want to isolate $a$ on one side of the equation. Here are the steps:

1. Combine like terms on both sides of the equation:

   $4000 + 5a = 3000 + 3000$ simplifies to $4000 + 5a = 6000$.

2. Subtract 4000 from both sides of the equation to isolate the term with $a$:

   \begin{align*} 4000 + 5a - 4000 &= 6000 - 4000 \\ 5a &= 2000 \end{align*}

3. Divide both sides by 5 to solve for $a$:

   \begin{align*} \frac{5a}{5} &= \frac{2000}{5} \\ a &= 400 \end{align*}

So, the solution to the equation is $a = 400$.
