Answer 3

Let's break down and solve this equation step by step:

1. First, simplify the division:

   4,900 ÷ 20 = 245

So, the equation becomes:

-390 + 245 - a + 40 = 10,000

2. Combine like terms on the left side of the equation:

-390 + 245 + 40 = -105

So, the equation becomes:

-105 - a = 10,000

3. Now, isolate 'a' by adding 105 to both sides of the equation:

-105 - a + 105 = 10,000 + 105

This simplifies to:

-a = 10,105

4. To solve for 'a,' multiply both sides by -1 to isolate 'a' on the left side:

-a * (-1) = 10,105 * (-1)

This simplifies to:

a = -10,105

So, the value of 'a' is -10,105.
