Let a and b are the digits of your number n, so that n = 10a + b.

The number after interchanging digits is 10b + a.

Then you have the system of two equations for the unknowns a and b:

.

Now, simplify it:

.

Simplify one more time:

.

Solve it.

b=7, a=3.

The number is 10a + b = 10*3+7 = 37.

Answer. 37.
