Calculation of the Father's Age

To calculate the age of Kyanan's father, we need to consider the information provided in the question. Let's break it down step by step:

1. The sum of Kyanan's age, his father's age, and his grandfather's age is 95. 2. Kyanan's father is 28 years younger than his grandfather. 3. Kyanan's father is 29 years older than Kyanan.

Let's assign variables to the unknown ages: - Kyanan's age: K - Kyanan's father's age: F - Kyanan's grandfather's age: G

Based on the given information, we can create the following equations:

1. Equation 1: K + F + G = 95 (the sum of their ages is 95) 2. Equation 2: F = G - 28 (Kyanan's father is 28 years younger than his grandfather) 3. Equation 3: F = K + 29 (Kyanan's father is 29 years older than Kyanan)

To find the age of Kyanan's father, we can substitute Equation 2 into Equation 1 and Equation 3:

K + (G - 28) + G = 95 (substituting Equation 2 into Equation 1)

Simplifying the equation:

2G + K - 28 = 95

2G + K = 123 (Equation 4)

G - 28 = K + 29 (substituting Equation 3 into Equation 2)

Simplifying the equation:

G - K = 57 (Equation 5)

Now we have a system of two equations (Equation 4 and Equation 5) with two variables (G and K). We can solve this system to find the values of G and K.

By solving the system of equations, we find that Kyanan's age (K) is 28 and his grandfather's age (G) is 85.

To find the age of Kyanan's father (F), we can substitute the values of K and G into Equation 3:

F = K + 29 = 28 + 29 = 57

Therefore, Kyanan's father is 57 years old.

Please note that the information provided in the question does not mention specific ages for Kyanan, his father, or his grandfather. The solution provided is based on the given equations and assumptions made from the question.
