Applying the equation, it is found that the solution for s is given by:
[tex]s = \frac{w - rh}{c}[/tex]
The equation we are going to work in this problem is given by:
[tex]cs + rh = w[/tex]
We want to solve for s, hence, we have to isolate s, first placing rh on the other side with the inverse signal(subtraction).
[tex]cs = w - rh[/tex]
Division is the inverse of multiplication, thus, c is multiplying s, it goes to the other side dividing:
[tex]s = \frac{w - rh}{c}[/tex]
Which is the solution for s.
