Step-by-step explanation:

The expression is given below as


|a+5|=-5-a

Concept:

We will apply the bsolute rule below


\begin{gathered} if|u|=a,a>0 \\ then,u=a,u=-a \end{gathered}

By applying the concept, we will have


\begin{gathered} \lvert a+5\rvert=-5-a \\ a+5=-5-a,a+5=5+a \\ a+a=-5-5,a-a=5-5 \\ 2a=-10,0=0 \\ (2a)/(2)=(-10)/(2),0=0 \\ a=-5,0=0 \end{gathered}

Hence,

The final answer is


a\leq-5
