Given:


(3)/(4)(x-2)\text{ }<\text{ x -2}

Opening the bracket:


(3x)/(4)\text{ - }(6)/(4)\text{ }<\text{ x - 2}

Collect like terms:


\begin{gathered} (3x)/(4)-x\text{ }<\text{ }(6)/(4)\text{ - 2} \\ (3x-4x)/(4)\text{ }<\text{ }(6-8)/(4) \\ -(x)/(4)\text{ }<\text{ }(-2)/(4) \end{gathered}

Solving for x:


\begin{gathered} -(x)/(4)\text{ }<\text{ }(-2)/(4) \\ -x\text{ }<\text{ -2} \\ x\text{ > 2} \end{gathered}

The solution in interval notation:


(2\text{ , }\infty\text{ )}

The solution on a graph:

The solution on a number line:
