    distance traveled

    The diameter of the large wheel of a tractor is 180cm and that of the small wheel is 50cm. what is the distance traveled by the tractor if the number of revolutions of the small wheel exceeds the number of turns of the large wheel by 2600 revolutions?

    s = distance traveled

    D = big wheel diameter

    d = little wheel diameter

    k = number of revolutions of the large wheel

    s = k \cdot \pi D

    s = (k+2600)\pi d

    solve the system for k , then determine s

    ... and the system of equations I've set up are exactly that, linear.
