Question

Solve for x in terms of r, s and t : s=2x+t/r

Answer 1

For this case we have the following equation:

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

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:

`rs =2x + t`

If we subtract "t" on both sides of the equation we have:

`rs-t = 2x`

If we divide by "2" on both sides of the equation we have:

`x = \frac {rs-t} {2}`

Thus, the value of the variable "x" is:

`x = \frac {rs-t} {2}`

Answer:

`x = \frac {rs-t} {2}`
