Simplifying (N + 6)(n + 7) = 0 Reorder the terms: (6 + N)(n + 7) = 0 Reorder the terms: (6 + N)(7 + n) = 0 Multiply (6 + N) * (7 + n) (6(7 + n) + N(7 + n)) = 0 ((7 * 6 + n * 6) + N(7 + n)) = 0 ((42 + 6n) + N(7 + n)) = 0 (42 + 6n + (7 * N + n * N)) = 0 (42 + 6n + (7N + nN)) = 0 Reorder the terms: (42 + 7N + 6n + nN) = 0 (42 + 7N + 6n + nN) = 0 Solving 42 + 7N + 6n + nN = 0 Solving for variable 'N'. Move all terms containing N to the left, all other terms to the right. Add '-42' to each side of the equation. 42 + 7N + 6n + -42 + nN = 0 + -42 Reorder the terms: 42 + -42 + 7N + 6n + nN = 0 + -42 Combine like terms: 42 + -42 = 0 0 + 7N + 6n + nN = 0 + -42 7N + 6n + nN = 0 + -42 Combine like terms: 0 + -42 = -42 7N + 6n + nN = -42 Add '-6n' to each side of the equation. 7N + 6n + -6n + nN = -42 + -6n Combine like terms: 6n + -6n = 0 7N + 0 + nN = -42 + -6n 7N + nN = -42 + -6n Reorder the terms: 42 + 7N + 6n + nN = -42 + -6n + 42 + 6n Reorder the terms: 42 + 7N + 6n + nN = -42 + 42 + -6n + 6n Combine like terms: -42 + 42 = 0 42 + 7N + 6n + nN = 0 + -6n + 6n 42 + 7N + 6n + nN = -6n + 6n Combine like terms: -6n + 6n = 0 42 + 7N + 6n + nN = 0 The solution to this equation could not be determined.
