The population y in the year x of the counties listed is approximated by the given equations, where x = 10 corresponds to 2010 and y is in thousands. Solve this system of equations, and interpre answer. County A: -x+20y = 108 County B: County C: -x+10y = 48 y = 6 Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. The system has exactly one solution. The solution is (12.6). (Type integers or fractions.) B. The system has infinitely many solutions of the form (y), where y is any real number. (Type integers or fractions.) C. The system has no solution. "What does the answer represent? Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. OA. Two counties had the same population of in the year OB. All three counties had the same population of in the year OC. There will be infinitely many times when the three counties will have the same population.
