Answer:
See below
Explanation:
Given
Solving for c
- Its not clear what the denominator is: c or c+r so doing both
Denominator is c:
- rv = 1/c + r
- 1/c = rv - r
- c = 1/(rv - r)
Denominator is c + r:
- rv = 1/(c + r)
- rv(c + r) = 1
- rvc + r²v = 1
- rvc = 1 - r²v
- c = (1 - r²v)/rv
or more simplified
