Consider the equation .  

  1. Stanley wants to start solving the equation by adding to both sides, while Terrence first wants to subtract from both sides. Will both strategies work? Is one strategy more efficient than the other?

    Solving the equation ultimately involves isolating to determine its value.
    If both strategies are working towards isolating through different methods, will both strategies work?

    Does one strategy require less work to isolate ?
    Is the strategy of adding to both sides rather than subtracting a more efficient and direct method?

    Both strategies work, but Stanley's strategy is more efficient because he isolates in a more direct manner.
