Answer 1

Answer:

48

Step-by-step explanation:

Let the number be represented by xy

y is the units digit

x is the tens digit

x+y=12.   the sum of the digits is 12

y=2x.      the units digit is twice the tens digit  

replacing y with 2x in the first equation we have  

x+2x=12

3x=12

x=4  

y=2x =2(4)=8  

xy = 48
