If [tex]V = \frac{12R}{r + R}[/tex], then R = ?

The answer is A. Vr / (12 - V).
To solve for R, we need to isolate it on one side of the equation. Here's how we can do it:
Multiply both sides by (r + R):
This eliminates the denominator on the right side, giving us:
V(r + R) = 12R
Distribute V on the left side:
Vr + VR = 12R
Subtract VR from both sides:
Vr = 12R - VR
Factor out R on the right side:
Vr = R(12 - V)
Divide both sides by (12 - V):
R = Vr / (12 - V)
Complete Question:
If V = 12 R / ( r + R ) then R=
A. Vr / ( 12 − V )
B. Vr + V /12
C. Vr − 12
D. V / r − 12
E. V ( r + 1 ) /12

To solve for R in the equation V = r + R 12 R ​ , we isolate R to get R = 12 − V V r ​ .
