Help me study for my Algebra class. I’m stuck and don’t understand.

**Please remember to show all work following standard mathematical practice:**

**1) Each step should show the COMPLETE expression or equation, not just a piece of it.**

**2) Each new step should follow logically from the step above it, following rules of algebra.**

**3) Each new step should be beneath the previous step.**

**4) The equal sign ( = ) should only connect equal numbers or expressions.**
