10x

10x is a phonetic way of abbreviating "thanks" (it should be read as "10-x" or "tenx" instead of "10 times"). Most people use it in messages, such as texts or social DMs.

For example, if someone texts you, "I dropped off your furniture in your backyard," you might reply with "10x!" Or, if someone DMs you about dropping off an item you purchased, you might reply with, "10x 4 ur help!"

10x is just one of many ways to thank others. Some examples that include numbers besides 10x are 10q and 3q.
