Algebra

Hi, Yesterday morning my class and I had algebraic equations, in algebra there are some things that are  special because in younger ages instead of using blank boxes you have to use letter that are y and x, These two are mostly often use, but once you get older they use different letter instead of x and y. Also in algebra whatever you do to one side you must do something to the other side it has to stay balance cause if you do it right right you might not the right answer so whatever you do to one side do it to the other side.
