Answer:
b = [tex]\frac{kv}{k+rt}[/tex]
Step-by-step explanation:
Given
k = [tex]\frac{brt}{v-b}[/tex] ← multiply both sides by (v - b)
k(v - b) = brt ← distribute left side
kv - kb = brt ( subtract brt from both sides )
kv - kb - brt = 0 ( subtract kv from both sides )
- kb - brt = - kv ( multiply through by - 1 to clear the negatives )
kb + brt = kv ← factor out b from each term on the left
b(k + rt ) = kv ← divide both sides by (k + rt )
b = [tex]\frac{kv}{k+rt}[/tex]
