Simplifying N(n + 1) + (n + 3) + (n + 5) = 39 Reorder the terms: N(1 + n) + (n + 3) + (n + 5) = 39 (1 * N + n * N) + (n + 3) + (n + 5) = 39 (1N + nN) + (n + 3) + (n + 5) = 39 Reorder the terms: 1N + nN + (3 + n) + (n + 5) = 39 Remove parenthesis around (3 + n) 1N + nN + 3 + n + (n + 5) = 39 Reorder the terms: 1N + nN + 3 + n + (5 + n) = 39 Remove parenthesis around (5 + n) 1N + nN + 3 + n + 5 + n = 39 Reorder the terms: 3 + 5 + 1N + n + n + nN = 39 Combine like terms: 3 + 5 = 8 8 + 1N + n + n + nN = 39 Combine like terms: n + n = 2n 8 + 1N + 2n + nN = 39 Solving 8 + 1N + 2n + nN = 39 Solving for variable 'N'. Move all terms containing N to the left, all other terms to the right. Add '-8' to each side of the equation. 8 + 1N + 2n + -8 + nN = 39 + -8 Reorder the terms: 8 + -8 + 1N + 2n + nN = 39 + -8 Combine like terms: 8 + -8 = 0 0 + 1N + 2n + nN = 39 + -8 1N + 2n + nN = 39 + -8 Combine like terms: 39 + -8 = 31 1N + 2n + nN = 31 Add '-2n' to each side of the equation. 1N + 2n + -2n + nN = 31 + -2n Combine like terms: 2n + -2n = 0 1N + 0 + nN = 31 + -2n 1N + nN = 31 + -2n Reorder the terms: -31 + 1N + 2n + nN = 31 + -2n + -31 + 2n Reorder the terms: -31 + 1N + 2n + nN = 31 + -31 + -2n + 2n Combine like terms: 31 + -31 = 0 -31 + 1N + 2n + nN = 0 + -2n + 2n -31 + 1N + 2n + nN = -2n + 2n Combine like terms: -2n + 2n = 0 -31 + 1N + 2n + nN = 0 The solution to this equation could not be determined.
