Teacher Script: "Let's look at this example together. We have the equation 2x - (-3) = x + 4. Remember, when we see a minus sign followed by a negative number in parentheses, it's the same as adding a positive number. So, our first step is to add 3 to both sides. Then, we'll subtract x from both sides to isolate our variable. Can you tell me what our final answer will be?"
