The second number of two numbers is 6 more than the first. The sum of the numbers is 26. What are the two numbers?

First, let's assign some expressions to represent these two numbers for the problem.

Let the first number be equal to x
Let the second number be equal to x + 6

Second, according to your problem, the sum of these two expressions will be equal to 26, therefore we now have the following equation:

x + x + 6 = 26
