Answer 3

To simplify the given expression, you can follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right).

Let's simplify your expression step by step:

1. Start by simplifying within the parentheses and brackets:

   First set of parentheses: 3(2x - 5 + 10x) becomes 3(12x - 5).

   Second set of parentheses and brackets: 10x(20 - a) - (-5a + 10) becomes 200x - 10ax + 5a - 10.

2. Distribute the 3 through the first set of parentheses: 3(12x - 5) = 36x - 15.

3. Now, we can rewrite the simplified expression with the distributed terms and combine like terms:

   36x - 15 + 200x - 10ax + 5a - 10.

4. Group like terms:

   (36x + 200x) + (-15 - 10) + (-10ax + 5a).

5. Combine like terms:

   236x - 25 - 10ax + 5a.

So, the simplified expression is:

236x - 10ax + 5a - 25.
