Answer 3

To simplify the expression -10 + 5(2a - 3) + 8a, 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). Here's how you simplify this expression step by step:

1. Start by applying the distributive property (multiplication) to the term inside the parentheses:

   5(2a - 3) = 10a - 15

2. Now, rewrite the expression with the distributed term:

   -10 + 10a - 15 + 8a

3. Next, combine like terms. Add the constants and combine the terms with 'a':

   (-10 - 15) + (10a + 8a) = -25 + 18a

So, the simplified expression is:

-25 + 18a
