If $2 n+5=16$, the expression $2 n-3$ equals
(A) 8
(B) 10
(C) 18
(D) 14
(E) 7
Since $2 n+5=16$, then $2 n-3=(2 n+5)-8=16-8=8$.

Alternatively, we could solve the equation $2 n+5=16$ to obtain $2 n=11$ or $n=\frac{11}{2}$.

From this, we see that $2 n-3=2\left(\frac{11}{2}\right)-3=11-3=8$.

ANSWER: (A)
