The sum of number a and number B is 13.2. If the decimal point of number a moves one place to the right, it is equal to number B. what are the two numbers?

Let the number a be x, then the number B be (13.2-x). According to the meaning of the question, we can get: 10x = 13.2-x, the solution is x = 1.2  13.2-x = 13.2-1.2 = 12, or: from the meaning of the question, we can get: the number B is 10 times of the number A. if the number a is x, then the number B is 10x. According to the meaning of the question, we can get x + 10x = 13.2
