Answer 1

$1\ \textless \ x+1\ \textless \ 5$
$\mathrm{Restar\:}1\mathrm{\:de\:toda\:la\:ecuacion}:$
$1-1\ \textless \ x+1-1\ \textless \ 5-1$
$0\ \textless \ x\ \textless \ 4$
$\begin{bmatrix}\mathrm{Solucion:}\:&\:0\ \textless \ x\ \textless \ 4\:\\ \:\mathrm{Notacion\:intervalo}&\:\left(0,\:4\right)\end{bmatrix}$
