Given:


2x\text{ + 8 > 18}

Step 1: Collect like terms


\begin{gathered} 2x\text{ > 18 - 8} \\ 2x\text{ > 10} \end{gathered}

Step 2: Divide both sides by 2:


\begin{gathered} (2x)/(2)\text{ > }(10)/(2) \\ x\text{ > 5} \end{gathered}

Hence the solution to the inequality is:


x\text{ > 5}

The graph of the inequality is shown below:
