When is |x-7| = 7-x?
Pick one
A) x>7  B) x<7  C) x=7  D) x<0  E) x<=7
When is |x-7| = 7-x?   Choice A: X=7, it is true but X cannot be always 7   Choice B: X=0, it is also true, but X cannot be always 0   Choice C: X&gt;7, it is false, for e.g. X=6, then one side of equation is 2 and the other side is -2   Choice D: X&lt;=7, this choice encapsulate Choice A, Choice B and for all other conditions and is true for above said equation. Hence the answer choice is x&lt;=7.
