There are $x$ cars, so the total number of people is $4x$. Since 4 people share one car, the number of people not in a car is $4(x-1)$. When 2 people share a car, there are 8 people left without a car to ride, so the number of people not in a car is $2(x-1)+8$. Since these two conditions are the same, set up the equation $4(x-1)=2(x-1)+8$.
