  3. Evaluate: 9x-7 <= 38

Expression: $9x-7 \leq 38$

Move the constant to the right-hand side and change its sign

$9x \leq 38+7$

Add the numbers

$9x \leq 45$

Divide both sides of the inequality by $9$

$\begin{align*}&x \leq 5 \\&\begin{array} { l }x \in \left\langle-\infty, 5\right]\end{array}\end{align*}$
