8-56.

Consider the equation

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 isolatingthrough different methods, will both strategies work?Does one strategy require fewer steps to isolate

? Is the strategy of addingto both sides rather than subtracting a more efficient and direct method? Solve

. Show your steps. Add 5 to both sides.
