Simplifying f(4) = f(n + -1) + 2(4) Reorder the terms for easier multiplication: 4f = f(n + -1) + 2(4) Reorder the terms: 4f = f(-1 + n) + 2(4) 4f = (-1 * f + n * f) + 2(4) 4f = (-1f + fn) + 2(4) Multiply 2 * 4 4f = -1f + fn + 8 Reorder the terms: 4f = 8 + -1f + fn Solving 4f = 8 + -1f + fn Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Add 'f' to each side of the equation. 4f + f = 8 + -1f + f + fn Combine like terms: 4f + f = 5f 5f = 8 + -1f + f + fn Combine like terms: -1f + f = 0 5f = 8 + 0 + fn 5f = 8 + fn Add '-1fn' to each side of the equation. 5f + -1fn = 8 + fn + -1fn Combine like terms: fn + -1fn = 0 5f + -1fn = 8 + 0 5f + -1fn = 8 Reorder the terms: -8 + 5f + -1fn = 8 + -8 Combine like terms: 8 + -8 = 0 -8 + 5f + -1fn = 0 The solution to this equation could not be determined.
