Problem

A picture $3$ feet across is hung in the center of a wall that is $19$ feet wall. How many feet from the end of the wall is the nearest edge of the picture?

$\text{(A)}\ 1\frac{1}{2} \qquad \text{(B)}\ 8 \qquad \text{(C)}\ 9\frac{1}{2} \qquad \text{(D)}\ 16 \qquad \text{(E)}\ 22$

Solution

Let's say that the distance from the picture to the wall is $x$ . Since that distance will be on both sides of the picture (it's in the exact middle), we can say that $\begin{align*}x + 3 + x = 19 &\Rightarrow 2x+3=19 \\&\Rightarrow 2x=16 \\&\Rightarrow x=8 \\\end{align*}$

$\boxed{\text{B}}$
