Key Concepts

Linear Equations

A linear equation is an equation in which each term is either a constant or a product of a constant and a single variable raised to the power of one. The main characteristic of a linear equation is that its graph is a straight line, and solving it usually involves isolating the variable on one side.

Isolating the Variable

Isolating the variable involves performing the same arithmetic operation on both sides of the equation to get the variable alone on one side. This process relies on the properties of equality and is fundamental in solving linear equations.

Solution Verification

Solution verification means substituting the computed solution back into the original equation to ensure that both sides of the equation agree. This step confirms that the solution obtained is indeed correct and that no mistakes were made during the solving process.
