-2f(n-1)+1=f(n)

Solution for -2f(n-1)+1=f(n) equation:

Simplifying
-2f(n + -1) + 1 = f(n)

Reorder the terms:
-2f(-1 + n) + 1 = f(n)
(-1 * -2f + n * -2f) + 1 = f(n)
(2f + -2fn) + 1 = f(n)

Reorder the terms:
1 + 2f + -2fn = f(n)

Multiply f * n
1 + 2f + -2fn = fn

Solving
1 + 2f + -2fn = fn

Solving for variable 'f'.

Move all terms containing f to the left, all other terms to the right.

Add '-1fn' to each side of the equation.
1 + 2f + -2fn + -1fn = fn + -1fn

Combine like terms: -2fn + -1fn = -3fn
1 + 2f + -3fn = fn + -1fn

Combine like terms: fn + -1fn = 0
1 + 2f + -3fn = 0

Add '-1' to each side of the equation.
1 + 2f + -1 + -3fn = 0 + -1

Reorder the terms:
1 + -1 + 2f + -3fn = 0 + -1

Combine like terms: 1 + -1 = 0
0 + 2f + -3fn = 0 + -1
2f + -3fn = 0 + -1

Combine like terms: 0 + -1 = -1
2f + -3fn = -1

Reorder the terms:
1 + 2f + -3fn = -1 + 1

Combine like terms: -1 + 1 = 0
1 + 2f + -3fn = 0
