Simplifying A(n) = -2 + (n + -1) * 5 Multiply A * n nA = -2 + (n + -1) * 5 Reorder the terms: nA = -2 + (-1 + n) * 5 Reorder the terms for easier multiplication: nA = -2 + 5(-1 + n) nA = -2 + (-1 * 5 + n * 5) nA = -2 + (-5 + 5n) Combine like terms: -2 + -5 = -7 nA = -7 + 5n Solving nA = -7 + 5n Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-5n' to each side of the equation. -5n + nA = -7 + 5n + -5n Combine like terms: 5n + -5n = 0 -5n + nA = -7 + 0 -5n + nA = -7 Reorder the terms: 7 + -5n + nA = -7 + 7 Combine like terms: -7 + 7 = 0 7 + -5n + nA = 0 The solution to this equation could not be determined.
