  1. The problem states that the total distance was 1356 miles -- so we assume that was the round trip mileage.

    x + x + 284 = 1356

    2x = 1072

    x = 536

  4. X+X-284 = 1356
    2x-284+284(cancel out). 1356-284
    2x÷2(cancel out) 1640÷2 = 820
    Check
    820+820-284 = 1356

  5. Total distance= 1356
    2 parts of the trip
    x= return trip

    1356=2x-284
    +284 +284
    1640=2x
    2 2

    820=x
