Teacher Script: "Now, let's look at this equation: 12(x/-5) = 144. What do you notice about the left side of the equation? That's right, we have a fraction inside parentheses being multiplied by 12. Our first step is to divide both sides by 12 to isolate the x/-5 term. Then, we'll multiply by -5 to isolate our variable. Can you work through the steps and tell me what our final answer will be? Remember to be careful when working with fractions and whole numbers in the same equation."
