If you remember to think it through in a logical and concrete way, you'll be able to solve the problem.? In this problem, you don't know what "x" is but you do know that it's less than zero. Therefore, you can solve this problem by picking any number that meets the condition of the question and evaluating all the terms with it. Solve the Problem 1. Since you don't know the exact value of "x," chose a number that meets its conditions. You know that "x" must be less than zero. So pick a negative number, such as -1.? 2. Substitute -1 for "x" in all the terms provided.? -2x=-2(-1)=2 -x=-(-1)=1 0=0 x=-1 2x=2(-1)=-2 3. After evaluating all the terms in the set with the "x" substitution, you get 2, 1, 0, -1, -2.? 4. The question asks for the smallest value in the set, which is -2. Therefore, the term that provided -2 (2x) is the smallest value.
