Hi,
I would need to solve the equation for “s”, keeping “s” also in the slider.
This is “s” must not affect “t”
Kindly please help.
Thanks

Manipulate[
 Solve[
  0.20 == 0.266 - 0.032 s + 0.00077 t],
 {t, 10, 50, Appearance -> "Labeled"},
 {s, 2, 2.8, Appearance -> "Labeled"}]

Your question is a bit hard to understand, but are you looking for something like this below?

Manipulate[
 	s = First@SolveValues[0.20 == 0.266 - 0.032 sx + 0.00077 t, sx],
 	{t, 10, 50, Appearance -> "Labeled"},
 	{s, 2.3, 3.3, Appearance -> "Labeled"}
 ]

Well, here is another:

Manipulate[
 	Grid[{
   		{"s(t):", First[sx /. Solve[0.20 == 0.266 - 0.032 sx + 0.00077 t, sx]]},
   		{"t(s):", First[tx /. Solve[0.20 == 0.266 - 0.032 s + 0.00077 tx, tx]]}
   	}],
 	{t, 10, 50, Appearance -> "Labeled"},
 	{s, 2.3, 3.3, Appearance -> "Labeled"}
 ]
