(1) Solve the formula for the specified variable

r = vx for r (the question is) v = ?

a = 1/3f * p for f (the question is) f = ?

(2) Solve the forulma for v

S = D + vm (the question is) v = ?

1. r = VX.

Divide both sides by X:

V = r/X.

a = (f/3)p

Multiply both sides by 3:

3a = fp,

Divide both sides by p:

f = 3a/p.

2. S = D + vm

Subtract D from both sides:

vm = S - D,

Divide both sides by m:

v = (S - D) / m
