Final answer:
When two factors in an equation are inversely proportional, changing one factor will result in a corresponding change in the other factor that maintains a constant product.
Step-by-step explanation:
When solving an equation, you can change two out of the three factors and still have the same product if the factors are inversely proportional to each other. This means that as one factor increases, the other factor decreases in such a way that their product remains constant.
For example, if we have the equation y = k/x, where k is a constant, we can change x and y in such a way that xy = k. If we double x, then y would be halved so that their product remains the same.
