The given equation is expressed as
[tex]\frac{5}{2x}\text{ = }\frac{25}{4}[/tex]The first step is to cross multiply. This means that we would multiply 5 with 4 and 2x with 25. It becomes
[tex]\begin{gathered} 50x\text{ = 20} \\ We\text{ would divide both sides of the equation by 50. it becomes} \\ x\text{ = }\frac{20}{50} \\ x\text{ = }\frac{2}{3} \end{gathered}[/tex]
