Question

Solve for the indicated variable A=r+rvf for v

Answer 1

Answer:

$v = \frac{A - r}{rf}$

Step-by-step explanation:

Given

$A = r + rvf$

Required

Solve for v

$A = r + rvf$

Subtract r from both sides

$A - r = r - r + rvf$

$A - r = rvf$

Divide both sides by rf

$\frac{A - r}{rf} = \frac{rvf}{rf}$

$\frac{A - r}{rf} = v$

Reorder the expression

$v = \frac{A - r}{rf}$

At this point, we;ve solved for v
