Let's designate number of tons which are transported by the plane for one flight for x. Then the first plane transported 2 tons, and the 5th and it was 1800 tons more than the second, than at the first. Let's work out and will solve the equation. 5x - 1800 = 2x 3x = 1800 x = 600 Then the first plane transported 600 * 2 = 1200 tons, and the second 600 * 5 = 3000. Answer: 1200 tons, 3000 tons.
