Calculation of the Number of Passengers in the Bus

To calculate the number of passengers in the bus before the stop, we need to consider the information provided.

According to the question, 10 passengers got off the bus at the stop, and z passengers got on the bus. After these changes, the total number of passengers in the bus became 12.

Let's assume that the initial number of passengers in the bus before the stop was x.

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

x - 10 + z = 12

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

Solving the Equation

To solve the equation, we can isolate x by moving the other terms to the other side of the equation:

x = 12 + 10 - z

Now, we can simplify the equation:

x = 22 - z

Therefore, the number of passengers in the bus before the stop can be calculated by subtracting the number of passengers who got on the bus (z) from 22.

Conclusion

The number of passengers in the bus before the stop can be calculated using the equation x = 22 - z.
