Final answer:
To solve the equation n+7=15, we subtract 7 from both sides of the equation, which gives us n=8. This is a basic algebraic operation where subtraction is used to isolate the variable n.
Step-by-step explanation:
The question n+7=15 is a basic algebraic equation where we are solving for the variable n. To find the value of n, we need to isolate it on one side of the equation. We can do this by subtracting 7 from both sides of the equation.
So, let's subtract 7 from both sides:
- n + 7 - 7 = 15 - 7
- n + 0 = 8
- n = 8
n equals 8, which is the solution to the equation. It's important to understand that we use inverse operations to isolate the variable, in this case, subtraction is the inverse of addition, allowing us to solve for n.
