Algebra is a branch of mathmatics that uses formulae to calculate unknowns
In linear algebra, Cramer's rule is an explicit formula for the solution of a system of linear equations with as many equations as unknowns, valid whenever the system has a unique solution.
Since "pre-" means before, then pre-algebra would be before algebra. Conversely, algebra would be after pre-algebra. Generally, the next class after a pre-algebra class would be Algebra I, followed by Algebra II.
The unknowns or variables
Pre-algebra preps you for algebra.2nd answer:Pre-AP-algebra is the same as Algebra I. Both are way harder than pre- algebra.

Well it would be like regular algebra, but there are more unknowns (which increases the difficulty exponentially)
They are variables or unknowns and are used in algebra.
Many. It is used to find unknowns and solve problems, which is an important part of life. If you get any job in science or math, it will be used regularly.

They are unknowns, or placeholders. The actual x and y are not significant. You could use any letter that you wanted, but the x and y are traditionally used so that everyone knows what they are.
