The distance between K and M = 35 (from the question)

(Reason: All individual distances in a line i.e. and sum up to give the distance ).

Collecting like terms:

, (Reason: All similar terms in an expression can be computed with one another i.e. added or subtracted).

Dividing by the variable's coefficient:

, (Reason: The coefficient is a similar factor to both terms in both sides, diving 40 by 4 gives you 10, hence the statement has been proven).
