Frank is x years old Millie is 12 years younger than frank three times Millie age is equal to 132

Answer: frank is 168 years

Step-by-step explanation:

Let the age of frank be x

While the age of millie is 12 times 3 younger than frank = 132 years

12 * 3 younger = 36 years younger

To find Frank's age, represent the scenario with the equation: x - (12*3) = 132

x - 36 = 132

x = 132 + 36

x = 168 years
