Simplifying An = (n + -1) * 2 + 3 Reorder the terms: nA = (-1 + n) * 2 + 3 Reorder the terms for easier multiplication: nA = 2(-1 + n) + 3 nA = (-1 * 2 + n * 2) + 3 nA = (-2 + 2n) + 3 Reorder the terms: nA = -2 + 3 + 2n Combine like terms: -2 + 3 = 1 nA = 1 + 2n Solving nA = 1 + 2n Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-2n' to each side of the equation. -2n + nA = 1 + 2n + -2n Combine like terms: 2n + -2n = 0 -2n + nA = 1 + 0 -2n + nA = 1 Reorder the terms: -1 + -2n + nA = 1 + -1 Combine like terms: 1 + -1 = 0 -1 + -2n + nA = 0 The solution to this equation could not be determined.
