Question

solve for $x$ and graph the solution on the number line below.$-7 \leq 2x + 7 \leq 31$answer attempt 1 out of 2$<$ $>$ $\leq$ $\geq$ orinequality notation:number line:click and drag to plot line.submit answer

Explanation:

Step1: Subtract 7 from all parts

$-7 - 7 \leq 2x + 7 - 7 \leq 31 - 7$
$-14 \leq 2x \leq 24$

Step2: Divide all parts by 2

$\frac{-14}{2} \leq \frac{2x}{2} \leq \frac{24}{2}$
$-7 \leq x \leq 12$

Answer:

Inequality Notation: $\boldsymbol{-7 \leq x \leq 12}$

For the number line: Plot a closed circle at $x=-7$ and $x=12$, then shade the region between these two points.
