Answer:

b = -
(a)/(a-1)

Explanation:

a =
(b)/(1+b) ( multiply both sides by 1 + b to clear the fraction )

a(1 + b) = b ← distribute parenthesis on left side

a + ab = b ( subtract b from both sides )

a + ab - b = 0 ( subtract a from both sides )

ab - b = - a ← factor out b from each term on left side

b(a - 1) = - a ( divide both sides by a - 1 )

b = -
(a)/(a-1)
