Answers:The equation is: n + (n+1) = 69The two numbers would be: 34 and 35Explanation:1 - obtaining the equation:Let the first number be nSince we know that the two numbers are consecutive, therefore, we know that they come directly after each otherThis would mean that the second number is n+1Now, we know that the sum of these two numbers is 69, this means that:n + (n+1) = 69 ..........> the necessary equation2 - getting the numbers:For two numbers, we will simply solve the equation that we got from the first part.n + (n+1) = 69n+1 + 1 = 692n = 68n = 34This means that:the first number (n) = 34the second number (n+1) = 35Hope this helps :)
