1) When finding a median, order your numerical list from smallest to larger, as so: 2,2,3,4,5,6,8,9. 2) Then start eliminating numbers from each side of the order; (The bolded numbers will be removed.) 2,2,3,4,5,6,8,9 2,3,4,5,6,8,9 2,3,4,5,6,8 3,4,5,6,8 3,4,5,6 4,5,6 4,5 3) Since there is an even number of digits in your list, you will have to add the last two digits and then divide them by two. 4 and 5 are the last numbers standing, (4+5=9)(9/2=4.5) and therefore your answer, would be 4.5, or B.
The left side of the equation is a restatement of the right side of the equation. It is true for all values of x. There are an infinite number of solutions.
