I got this ratio problem:

$$6:2::8:x$$

As someone who has a difficult time with even basic math, I'm kind of confused about this bit :: Would that be the same as saying $6:2 = 8:x$?

Yes both are same.

One other way to do -

1st term × 4th term = 2nd term × 3rd term

6x = 2 × 8

6x = 16

Solve for x.
