If the sum of a number and 8 is 15, what is the number?

The correct answer is: 7

To solve the problem, you begin with the equation that represents the given information. The sum of a number (which we can represent as "x") and 8 equals 15 can be expressed as: x + 8 = 15 Next, the goal is to isolate the variable x. You can do this by subtracting 8 from both sides of the equation: x + 8 - 8 = 15 - 8 This simplifies to: x = 7 So, the number that satisfies the equation is 7. This option correctly reflects the solution derived from manipulating the initial equation based on the problem's requirements.
