Kelly tells you that when variables are in the denominator, the equation 3 over 4 plus 2 over x equals 5 over 8 becomes unsolvable. Kelly explains, "There is a value for x that makes the zero and you can't divide by zero." Demonstrate to Kelly how the equation is still solvable and explain your reasoning

21.4 i did it already for s1

step-by-step explanation:

change of stock price/initial stock price on friday * total stock value = change of stock value

total stock value at initial stock price on friday/ initial stock price on friday = number of shares

3539.04/73.73 = 48 shares
