I will rewrite the wording and write out the equation as it goes so there is better understanding. Once I do that, I will solve it for you. Nine times a number (9n) is (=) one more than ten times the number (10n + 1). Now that we've rewritten it, let's only write what we have in parenthesis. 9n = 10n + 1. Now that we have our equation, let's solve! 9n = 10n + 1 Subtract 10n from both sides. -1n = 1 Divide both sides by -1. n = -1 I hope this helps!
