Solve the inequality
[tex]\begin{gathered} 2x+12>26 \\ \text{Subtract 12 from both sides and you'll have} \\ 2x+12-12>26-12 \\ 2x>14 \\ \text{Divide both sides by 2} \\ \frac{2x}{2}>\frac{14}{2} \\ x>7 \end{gathered}[/tex]Therefore, the solution to the inequality is
[tex]x>7[/tex]And this is plotted on a number line as shown;
The open circle (or unshaded dot) on the graph indicates that all the values of x does not include 7, but all values of x are greater than 7
