For this case we have the following equation:
[tex]s = \frac {2x + t} {r}[/tex]
We must clear the value of the variable "x" as a function of r, s and t:
If we multiply by "r" on both sides of the equation we have:
[tex]rs =2x + t[/tex]
If we subtract "t" on both sides of the equation we have:
[tex]rs-t = 2x[/tex]
If we divide by "2" on both sides of the equation we have:
[tex]x = \frac {rs-t} {2}[/tex]
Thus, the value of the variable "x" is:
[tex]x = \frac {rs-t} {2}[/tex]
Answer:
[tex]x = \frac {rs-t} {2}[/tex]
