Question

Rewrite the equation C = 2nr to show the expression that can be used to find the value of r.

Answer 1

C = 2nr

you divide by 2n both sides

that means C/2n = 2nr/2n

after that you simplify then it will be C/2n = r

r = C/2n

Answer 2

The process is:

C = 2nr

2nr = c

r (2n) = c

`r = (c)/(2n)`

That's the answer☝️☝️☝️☝️

or maybe this one

r = 2n + c

sorry, I'm unsure, it has been too long since I studied that...
