Question

Solve for n.
n + 1 = 4(n - 8)
O
n=1
On=8
O n= 11
O
n=16

Answer 1

n = 11

Explanation:

n + 1 = 4(n - 8)

n + 1 = 4n - 32 [Multiply 4 times (n-8)]

1 = 3n - 32 [Subtract 1n from both sides]

33 = 3n [Add 32 to both sides]

3n = 33

n = 11

CHECK:

Does n + 1 = 4(n - 8) when n = 11?

n + 1 = 4(n - 8)

11 + 1 = 4(11 - 8)

11 + 1 = 4(3)

12 = 12 YES
