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

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

5 n = 8 n + 30

3 n = 30

5 n + 8 n = 30

The number is - 10.

Step-by-step explanation:

Let the "number" be x.

5x=8x+30

30=5x-8x

30=-3x

x=30/-3

x=-10

5n=8n+30, which is - 10

Step-by-step explanation:

so five times a number, so 5n is the same (or equal to) so 5n = ... 30 more than 8 times the number (8n+30) so we get 5n=8n+30. solving this results in - 3x=30, so x=-10
