2000 AMC 12 Problems/Problem 5

From AoPSWiki

Problem

If |x - 2| = p, where x < 2, then x - p =

\mathrm{(A) \ -2 } \qquad \mathrm{(B) \ 2 } \qquad \mathrm{(C) \ 2-2p } \qquad \mathrm{(D) \ 2p-2 } \qquad \mathrm{(E) \ |2p-...

Solution

When x < 2, x-2 is negative so |x - 2| = 2-x = p and x = 2-p.

Thus x-p = (2-p)-p = 2-2p \Longrightarrow \mathrm{(C)}.
