Understand the problem:  Step 1: Understand the problem. Kelsey's grandfather said the tortoise was 48 years old when Kelsey was born, which was 12 years ago. We need to find the tortoise's current age, t. Set up the equation:  Step 2: Set up the equation. The tortoise's age 12 years ago was 48 years. To find its current age, we add 12 years to 48. The correct equation is t - 12 = 48. Solve the equation:  Step 3: Solve the equation. Add 12 to both sides of the equation: t - 12 + 12 = 48 + 12 t = 60
