degree

The degree of an equation refers to the highest power of the variable in the equation. For example, a linear equation, which is of the first degree, involves variables raised only to the power of one. An equation like (ax + b = c) is a first-degree equation in the variable (x). Equations can be linear in some variables but not others, such as (x + y^2 = 0), which is linear in (x) but not in (y). Systems of equations that share a common solution are called simultaneous equations, and their solutions can be visualized as the intersection points of the lines or planes they represent. Elementary algebra, a fundamental branch of mathematics, deals with the general properties of numbers and their relationships, using symbols to represent quantities and operations.12
