A plane was originally flying at an altitude of x feet when it ascended 2,000 feet and then descended 5,000 feet. If the plane's altitude after these two changes was its original altitude, then the solution of which of the following equations gives the plane's original altitude, in feet ?

(A) x+2,000=1/3(x-3,000)
(B) 1/3(x-3,000)=x
(C) x+3,000=1/3x
(D) x-7,000=1/3x
(E) x-3,000=1/3x
