On the day of the FEA field trip, two other school clubs, the Environmental Club and the Drama Club, are also planning field trips. Each group had to report the number of people going on their field trip so the cafeteria would know how many meals to make that day. The cafeteria manager knows 105 students will be absent for field trips. The principal knows that there are twice as many students in the Drama Club as in the FEA club and 10 more students in the Environmental Club than in the Drama Club. Write and solve an equation to find out how many students will be on the FEA field trip. ( steps please )
