Son's age: x years
Father's age: y years
Equation 1: y = 3 + 3x
Equation 2: y + 3 = 2(x + 3) + 10
Substituting equation 1 into equation 2: 3 + 3x + 3 = 2(x + 3) + 10
Combining like terms: 3x + 6 = 2x + 16
Subtracting 2x from both sides: x + 6 = 16
Subtracting 6 from both sides: x = 10
Substituting this value for x into equation 1: y = 3 + 3x
Substituting 10 for x: y = 3 + 3 * 10
Simplifying: y = 3 + 30
Simplifying further: y = 33
Therefore, the father's present age is 33 years.
