Answer:
64
Step-by-step explanation:
Hello, we can write this two digit number 'ab', a and b being positive integer between 0 and 9.
For instance , 54, a = 5 and b =4
The number can be written 10*a+b (54=5*10+4, for instance)
The sum of a two digit number is 10.
a + b = 10
The value of the number is 16 times the units digit.
10a + b = 16b <=> 10a = 16b - b = 15b
and then, b = 10 - 6 = 4.
So the solution is 64.
Thank you
