Question

if s=2x+t/r what does it equala. s/r-2x. b.sr/2x. c. sr+2x. d.sr-2rx

Answer 1

given expression :

$s=2x+\frac{t}{r}$

Since, in the given option, there is no t- variiable, So, we solve th egiven expression for t,

$\begin{gathered} s=2x+\frac{t}{r} \\ \text{Taking LCM on left side} \\ s=\frac{2rx+t}{r} \\ \text{Apply cross multiplication,} \\ sr=2rx+t \\ t=sr-2rx \end{gathered}$

Answer : (d). sr-2rx
