Question

Flve times a number is the same as 30 more than 8 times the number. Find the number.

If nis "the number," which equation could be used to solve for the number?

Answer 1

5N = 8N + 30
-8N = 30
-3N = 30
divide both sides by -3
N = -10

N stands for number as the unknown. Most people use X, but I use N. Very sorry if this is incorrect, but it’s the only way I know how to do these kind of problems.

Answer 2

5n = 8n + 30 OR

-3n = 30

Explanation:

5n = 8n + 30

Subtract 8n from both sides

-3n = 30

Divide both sides by -3

n = -10
