Answer:
r = (x - 10m)/w
Step-by-step explanation:
Isolate the variable, r. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, subtract 10m from both sides of the equation:
rw + 10m (-10m) = x (-10m)
rw = x - 10m
Next, divide w from both sides:
(rw)/w = (x - 10m)/w
r = (x - 10m)/w
r = (x - 10m)/w is your answer.
