Answer 1

$Solution, 4d+7\le \:23\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:d\le \:4\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:4]\end{bmatrix}$

$Steps:$

$4d+7\le \:23$

$\mathrm{Subtract\:}7\mathrm{\:from\:both\:sides},\\4d+7-7\le \:23-7$

$\mathrm{Simplify},\\4d\le \:16$

$\mathrm{Divide\:both\:sides\:by\:}4,\\\frac{4d}{4}\le \frac{16}{4}$

$\mathrm{Simplify},\\d\le \:4$

$\mathrm{The\:Correct\:Answer\:is\:d\le \:4}$
