Answer

$p=-3$

Work Step by Step

$\begin{align*} -14+11&=p-11+11&\text{Add 11 to each side of the equation.}\\ -3&=p &\text{Simplify}. \end{align*}$ Check if the solution is correct by substituting $-3$ to the variable in the original equation: $\begin{align*} -14&=p-11\\ -14&\stackrel{?}{=}-3-11\\ -14&\stackrel{\checkmark}{=}-14 \end{align*}$ Thus, the solution is $p=-3$.
