- The first step to solve 11x-7=9x+3 for x, is to add 7 to both sides of the equation.
- 02:05
- We add 7 to both sides because we have to combine like terms and what we do to one side of an equation we have to do to the other side.

- Hey Doug, I think you're close on this problem. But I feel like we should subtract 9x instead of adding it. Let's take a look and try again.

- You're right Molly! Thanks for catching that and helping me!
