Consider the following set of equations: equation a: y = −x + 5 equation b: y = 6x − 2 which of the following is a step that can be used to find the solution to the set of equations? −x = 6x + 2 −x − 2 = 6x + 5 −x + 5 = 6x – 2 −x + 5 = 5x

The solution set for 5v2 – 125 = 0 is

Asays "we are both knaves" and b says nothing. exercises 24–31 relate to inhabitants of an island on which there are three kinds of people: knights who always tell the truth, knaves who always lie, and spies (called normals by smullyan [sm78]) who can either lie or tell the truth. you encounter three people, a, b, and c. you know one of these people is a knight, one is a knave, and one is a spy. each of the three people knows the type of person each of other two is. for each of these situations, if possible, determine whether there is a unique solution and determine who the knave, knight, and spy are. when there is no unique solution, list all possible solutions or state that there are no solutions. 24. a says "c is the knave," b says, "a is the knight," and c says "i am the spy."
