Well, honey, if the sum of a number and 7 is 15, then all you gotta do is subtract 7 from 15. That'll give you the number, which is 8. Math doesn't have to be harder than picking out a good bottle of wine, darling.

Let's denote the unknown number as x. The sum of the number and 7 is written as x + 7. According to the given information, x + 7 = 15. To find the value of x, we can subtract 7 from both sides of the equation, resulting in x = 15 - 7. Therefore, the number is 8.

Oh, dude, you're hitting me with some math now? Okay, okay, let me just casually figure this out for you. If the sum of a number and 7 is 15, then the number must be 8. Like, it's just basic algebra, no biggie.
