Linear equation: In this section we give a

In this section we give a process for solving linear equations , including equations with rational expressions, and we illustrate the process with several examples. In addition, we discuss a subtlety involved in solving equations that students often overlook. A linear equation is an algebraic equation that forms a straight line when graphed. Each term is either a constant, or the product of a constant and a single variable. A linear equation can have one or more dependent variables. For example, the following equation expresses the total cost of buying ... A linear equation is an equation that describes a straight line on a graph. Explore and learn more about linear equations with concepts, definitions, facts, examples, and solutions. Learn what linear equations are, how to write them in different forms, and how to solve them in one, two, or three variables. Find examples, practice questions, and FAQs on linear equations.
