Answer:
n + 3 = 8
Step-by-step explanation:
"n" is the number, "Three more than a number is 8" means that the question is a addition equation. Three more than "n" means plus 3 to n. In this case, we already know it's an addition equation and 8 is the sum, so the equation will be:
n + 3 = 8
or
3 + n = 8
