Translate this situation into a system of equations of the first degree in two variables and make sure you identify the variables clearly:
Today, the difference in age between a father and his son is 23 years. Two years from now, the father's age will be double the age of his son in two years' time.

Math 
Steve,
f = s+23
f+2 = 2(s+2)
