1. Solving Multi-Step Equations
Using your properties to get the answer

2. Equations vs. Expressions
There are different rules you have to follow depending on where the equal sign is located.
Expressions do NOT have =.
Equations HAVE = signs.
If you are moving terms from one side to the other, adding its inverse is necessary.
If you are combining like terms that are on the same side, just combine them (like terms).
