given expression :
[tex]s=2x+\frac{t}{r}[/tex]Since, in the given option, there is no t- variiable, So, we solve th egiven expression for t,
[tex]\begin{gathered} s=2x+\frac{t}{r} \\ \text{Taking LCM on left side} \\ s=\frac{2rx+t}{r} \\ \text{Apply cross multiplication,} \\ sr=2rx+t \\ t=sr-2rx \end{gathered}[/tex]Answer : (d). sr-2rx
