Algebra is all about solving for the unknown. If you want to do algebra it’s easy. The quickest and simplest way to solve for the unknown is to move everything that is known to one side and everything that is unknown to the other side. For instance, x + 5 = 9. 9 and 5 are known so move them to the same side of the equal sign together. Now this next step is very important. Think of the equal sign as a mirror. Whenever you move something from one side to the other you must change the sign. If it’s positive on one side when you move it then it becomes negative on the other side. When you move the 5 to the other side of the equal sign it becomes x = 9 – 5. Your answer is x is equal to 4. Congratulations, you just did algebra!
