Answer : x = 7


\begin{gathered} \text{Solve for x: }\frac{x\text{ - 5}}{4}\text{ = }(1)/(2) \\ \text{Firstly, introduce cross multiplication} \\ 2(x\text{ - 5) = 4 x 1} \\ \text{Open the parenthesis} \\ 2\cdot x\text{ - 2}\cdot5\text{ = 4} \\ 2x\text{ - 10 = 4} \\ \text{Make 2x the subject of the formula} \\ 2x\text{ = 4 + 10} \\ 2x\text{ = 14} \\ \text{Divide both sides by 2} \\ (2x)/(2)\text{ = }(14)/(2) \\ x\text{ = 7} \end{gathered}
