Simplifying (N + 4)(n + 7) = -2 Reorder the terms: (4 + N)(n + 7) = -2 Reorder the terms: (4 + N)(7 + n) = -2 Multiply (4 + N) * (7 + n) (4(7 + n) + N(7 + n)) = -2 ((7 * 4 + n * 4) + N(7 + n)) = -2 ((28 + 4n) + N(7 + n)) = -2 (28 + 4n + (7 * N + n * N)) = -2 (28 + 4n + (7N + nN)) = -2 Reorder the terms: (28 + 7N + 4n + nN) = -2 (28 + 7N + 4n + nN) = -2 Solving 28 + 7N + 4n + nN = -2 Solving for variable 'N'. Move all terms containing N to the left, all other terms to the right. Add '-28' to each side of the equation. 28 + 7N + 4n + -28 + nN = -2 + -28 Reorder the terms: 28 + -28 + 7N + 4n + nN = -2 + -28 Combine like terms: 28 + -28 = 0 0 + 7N + 4n + nN = -2 + -28 7N + 4n + nN = -2 + -28 Combine like terms: -2 + -28 = -30 7N + 4n + nN = -30 Add '-4n' to each side of the equation. 7N + 4n + -4n + nN = -30 + -4n Combine like terms: 4n + -4n = 0 7N + 0 + nN = -30 + -4n 7N + nN = -30 + -4n Reorder the terms: 30 + 7N + 4n + nN = -30 + -4n + 30 + 4n Reorder the terms: 30 + 7N + 4n + nN = -30 + 30 + -4n + 4n Combine like terms: -30 + 30 = 0 30 + 7N + 4n + nN = 0 + -4n + 4n 30 + 7N + 4n + nN = -4n + 4n Combine like terms: -4n + 4n = 0 30 + 7N + 4n + nN = 0 The solution to this equation could not be determined.
