Solve the problem.In one study the maximum heart rates of conditioned athletes were examined. A group of athletes was exercised to exhaustion. Let x represent an athlete's heart rate five seconds after stopping exercise and y represent an athlete's heart rate ten seconds after stopping exercise. It was found that the maximum heart rate H for these athletes satisfied the following two equations.  H = 0.491 x + 0.468 y + 11.2  H = -0.981 x + 1.872y + 26.4If an athlete had a maximum heart rate of H = 158, determine the value of y graphically to the tenths place.

A. y = 152.1 B. y = 151.4 C. y = 151.8 D. y = 147.7
