Solve the formula for the indicated variable-
S = L(1-r), for r

r=

Step-by-step explanation:

You would want to isolate the r by itself by doing all the opposite operations.

First, you can divide the L to get

1-r =

Next, move the 1 to the other side to get

-r=

Then, we would not want to keep the negative so, move it to the other side to get

r=

(Note the 1 changed to a positive because we move the negative to the other side so, negative or negative 1 will be positive.
