To find the two-digit number, we need to determine the tens digit and the units digit.
Let's assume the tens digit is 'x' and the units digit is 'y'.
Given that the sum of the digits is 12, we can write the equation: x + y = 12.
We are also told that the units digit is twice the tens digit, so we can write the equation: y = 2x.
To solve these equations, we can substitute the value of y from the second equation into the first equation:
x + 2x = 12.
Combining like terms, we get: 3x = 12.
Dividing both sides by 3, we find: x = 4.
Substituting the value of x back into the second equation, we have: y = 2 * 4 = 8.
Therefore, the two-digit number can be formed as 48.
