**Let's start with an easy one:**

**Solve **

**We can just look at it and see that x = 10...**

**But, what if we didn't see that? What would we do?**

**Here's the Algebra trick:**

**We'll add 3 to both sides!**

***Remember the see saw?Whatever we do to one side of the equation,we have to do to the other side.**

**Why did we ADD 3?**

** To undo this! + is the opposite of -**

**The goal is to get the x alone. Just imagine that Mr. X hasn't showered in a few weeks and everyone wants to get away from him. It's your job to help.**
