Final answer:
The expression (13x - 14) - (12x - 23) simplifies to x + 9 after distributing the negative sign to each term in the second parentheses then combining like terms.
Step-by-step explanation:
The question is asking to subtract two algebraic expressions. This problem falls under the subject of mathematics, specifically algebra, and is commonly encountered at a high school level.
To subtract (13x - 14) - (12x - 23), we start with the x values. Here's how you do it: 13x (from the first bracket) minus 12x (from the second bracket) equals x. Then move on to the numbers. You have -14 (from the first bracket), and you subtract -23 (from the second bracket), which is the same as adding 23, giving you 9. So, the answer is x + 9, which is not an option in the choices given. It might be a typo in your problem.
Remember, when dealing with subtraction of an entire term, distribute the minus sign to each term in the parentheses before subtracting. In other words, change the sign of each term in the second parentheses, then combine like terms.
