3 times a number plus 12 minus 5 times the same number is 22. What is the number?

If you would like to find the number, you can calculate this using the following steps:

n = ? ... a number

3 times a number plus 12 minus 5 times the same number is 22

3 * n + 12 - 5 * n = 22

3 * n - 5 * n = 22 - 12

-2 * n = 10

2 * n = - 10

n = - 10/2

n = - 5

The correct result would be - 5.
