If they are equal numbers then n = n Hence n + n = 54 2n = 54 n = 54/2 n = 27 So 27 + 27 = 54

no
n/2 = 60 Therefore, n = 60 x 2 n = 120

5/(n - 12) = 10(n + 5) (multiply by the common denominator (n - 120(n + 9) to both sides)[5/(n - 12)][(n - 12)(n + 9)] = [10(n + 5)][(n - 120)(n + 9)] (simplify)5(n + 9) = 10(n - 12)5n + 45 = 10n - 120 (subtract 5n and add 120 to both sides)5n - 5n + 120 + 45 = 10n - 5n + 120 - 120165 = 5n (divide by 5 to both sides)33 = n

x to the n divided by x to the n is 1. By the law of powers x to the power n divided by x to the power n is x to the power (n minus n), ie x to the power zero. Things which are equal to the same thing are equal to each other. Therefore x to the power zero = 1. (Unless x = zero!)
