If 2/z = 2/(z + 1) + 2/(z + 64) which of these integers could be the value of z? Choose the correct choice from the following options
A) 0	B) 1	C) 2	D) 5	E) 8
Solving for z algebraically in this problem would not be easy. Instead, we can follow the hint in the question (“which of these integers…”) and test each answer choice:   A. 2/0 = 2/1 +2/64 INCORRECT (Division by zero)   B. 2/1 = 2/2 +2/65 INCORRECT   C. 2/2 = 2/3 +2/66 INCORRECT   D. 2/3 = 2/4 +2/69 INCORRECT   E. 2/4 = 2/5 +2/72 CORRECT   The correct answer is E, because it contains the only value that makes the equation work. Notice how quickly this strategy worked in this case
