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.
