Question

What should be added to twice the rational number -4/x to get 5/4?

Answer 1

Answer :

Let we add " y " to twice the rational number $-\frac{4}{x}$ to get $\frac{5}{4}$ , . We get

$$\begin{gathered} 2\left(-\frac{4}{x}\right)+y=\frac{5}{4} \\ \Rightarrow -\frac{8}{x}+y=\frac{5}{4} \\ \Rightarrow y=\frac{5}{4}+\frac{8}{x} \\ \Rightarrow y=\frac{\mathbf{5}\mathbf{x}\mathbf{}\mathbf{+}\mathbf{}\mathbf{32}}{\mathbf{4}\mathbf{x}}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{(}\mathbf{}\mathbf{Ans}\mathbf{}\mathbf{)} \end{gathered}$$
