You have two equations and two unknowns.

x+y = 38
x*y = 280

Rearranging the first one, y= 38-x. Substituting that into the second gives

x * (38-x) = 280

Multiplying that out, you're looking for the solution to the equation

-1x*x + 38x - 280 = 0.

The roots of that equation are 10 and 28, so there are your answers.
