The sum of a and B is 171.6. If the decimal point of B moves one place to the right, it is equal to A. how many are a and B

If the decimal point of number B moves one place to the right, it is equal to number a,
Let B be x, then a be 10x
x+10x=171.6
x=15.6
The numbers of a and B are 156 and 15.6 respectively
