Simplifying N(n + 1) = 90 Reorder the terms: N(1 + n) = 90 (1 * N + n * N) = 90 (1N + nN) = 90 Solving 1N + nN = 90 Solving for variable 'N'. Move all terms containing N to the left, all other terms to the right. Reorder the terms: -90 + 1N + nN = 90 + -90 Combine like terms: 90 + -90 = 0 -90 + 1N + nN = 0 The solution to this equation could not be determined.
