Let the first digit of the 2-digit number be x and the second digit be y.
Then the ratio (x/y) equals (1/2). Write a formula for y in terms of x.

The tens digit is 2 more than the units digit. Using the letters x and y, write out the proper equation.

Now solve your two equations simultaneously for x and y.
