The Bailey family planned a trip to a drive-in movie theater and 42 family members attend. Seven cars filled and 7 more people traveled in a truck. How many people were in each car?

Answer:5 people were in each car.

Step-by-step explanation:

Let x represent the number of people that travelled in each car.

The total number of people in the Bailey family that made the trip to the drive-in movie theater was 42.

Seven cars filled and 7 more people traveled in a truck. This means that

7x + 7 = 42

Subtracting 7 from the left hand side and the right hand side of the equation. It becomes

7x + 7 - 7 = 42 - 7

7x = 35

Dividing the left hand side and the right hand side of the equation by 7, it becomes

7x/7 = 35/7

x = 5
