At 6:00 P.M., the temperature was 94 degrees. Before it rose by 6 degrees (from 3:00 P.M. to 6:00 P.M.), it must have been 94 - 6 = 88 degrees. Since the temperature at 3:00 P.M. was double what it was at noon, it means the temperature at noon was 88 / 2 = 44 degrees. Since the temperature rose 7 degrees from 10:00 A.M. to noon, the temperature at 10:00 A.M. was 44 - 7 = 37 degrees.
