Rearrange (r+s)/8s=(r-s)/8n to make r the subject.
OK, I have started by rearranging the formula:
8n(r+s)=8s(r-s)
8nr+8ns=8sr-8s^2
What do I do next?
all been clarified, thanks
Next, we can gather all the terms containing "r" on one side of the equation by subtracting 8nr from both sides:
8ns = 8sr - 8s^2 - 8nr
Now, let's factor out "r" on the right side of the equation:
8ns = r(8s - 8n - 8s^2)
To isolate "r," divide both sides of the equation by (8s - 8n - 8s^2):
r = 8ns / (8s - 8n - 8s^2)
And that's the rearranged equation with "r" as the subject.
