b(n)=-4-2(n-1)

Solution

b (n) = - 4 - 2 (n - 1)

Solution

n = - \frac{2}{b + 2}; b \neq = - 2

Solution steps

b (n) = - 4 - 2 (n - 1)

Expand

b (n) : bn

Expand

- 4 - 2 (n - 1) : - 2 n - 2

bn = - 2 n - 2

Move

2 n

to the left side

bn + 2 n = - 2

Factor

bn + 2 n : n (b + 2)

n (b + 2) = - 2

Divide both sides by

b + 2; b \neq = - 2

n = - \frac{2}{b + 2}; b \neq = - 2
