Problem Analysis

To solve this problem, we need to determine the initial number of cars in the garage. We are given that 30 cars left the garage, and the number of cars remaining in the garage is 12 less than the number that left. Let's use algebra to solve this problem.

Solution

Let's assume the initial number of cars in the garage is x.

According to the problem, 30 cars left the garage, so the number of cars remaining in the garage is x - 12.

We can set up the following equation to represent the given information:

x - 12 = 30

To find the value of x, we can solve this equation.

Solving the Equation

To solve the equation, we can add 12 to both sides:

x - 12 + 12 = 30 + 12

Simplifying the equation:

x = 42

Answer

Therefore, the initial number of cars in the garage was 42.
