Answer:
Follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication, Division from left to right, and Addition and Subtraction from left to right).
Explanation:
Step 1: Parentheses
We have the expression (8x + 24) inside parentheses. To simplify within the parentheses, we can combine like terms. Since there are no like terms to combine, we can rewrite this as 8x + 24.
Step 2: Multiplication
Next, we can distribute the -1 outside the parentheses to each term within the parentheses. Multiplying -1 by 8x gives us -8x, and multiplying -1 by 24 gives us -24. The expression now becomes -8x + 24.
Step 3: Addition and Subtraction
Now, we can combine like terms in the expression. We have -27 + (-8x + 24) - 7x. Combining -27 and 24 gives us -3. So, the expression becomes -3 + (-8x) - 7x.
Step 4: Combine Like Terms
Finally, we can combine the like terms -8x and -7x, which gives us -15x. So, the final simplified expression is -3 - 15x.
