Answer:

x=142

Step-by-step explanation:

The given equation is:


\frac{\sqrt[]{x+2}}{3}=4

Cross multiply


\begin{gathered} \sqrt[]{x+2}=3(4) \\ \sqrt[]{x+2}=12 \end{gathered}

Square both sides


\begin{gathered} \sqrt[]{x+2}^2=12^2 \\ \end{gathered}

Note that the root cancels the square root


x+2=144

Collect like terms


\begin{gathered} x=144-2 \\ x=142 \end{gathered}
