Answer
This inequality holds for all real numbers.
Its equivalent interval notation is $(-\infty, \infty)$.
Work Step by Step
$3(x + 5)$ + $1$ $\geq$ $5 + 3x$
$3x + 15 + 1$ $\geq$ $5 + 3x$
$16$ $\geq$ $5$
$11$ $\geq$ $0$
This inequality holds for all real numbers.
Its equivalent interval notation is $(-\infty, \infty)$.
