The Big Screamer Coaster carries 92 people altogether. Some of its cars carry 4 passengers, and the rest carry 6 passengers. There are three less 6-passenger cars than 4-passenger cars. How many 4-passenger cars are there?

Let x=number of 4-passenger cars
4x+6(x-3)=92, solve for x
Thank you sooooo much for the help. I really needed it.
