Final answer:
The equation that could be used to solve for the value of n if n + 2 = 6 is 6 - 2 = n. To solve for n, we need to isolate the variable.
Step-by-step explanation:
The equation that could be used to solve for the value of n if n + 2 = 6 is 6 - 2 = n.
To solve for n, we need to isolate the variable.
So, we subtract 2 from both sides of the equation.
This gives us n = 6 - 2, which simplifies to n = 4.
