To solve the problem in question 15 from the image:

There are 40 passengers in the bus and fewer in the trolleybus. The bus has 6 more passengers than the trolleybus. How many passengers are in the trolleybus?

Let \( x \) represent the number of passengers in the trolleybus.

The problem states that the bus has 6 more passengers than the trolleybus, so we can express the number of passengers in the bus as \( x + 6 \).

Since the total number of passengers in both vehicles is 40, we can write the equation:

\[ x + (x + 6) = 40 \]

Solving this equation:

1. Combine like terms: \[ 2x + 6 = 40 \]

2. Subtract 6 from both sides: \[ 2x = 34 \]

3. Divide by 2: \[ x = 17 \]

Therefore, there are 17 passengers in the trolleybus.
