Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Linear Equations
A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and a single variable. The general form is ax + b = c, where a, b, and c are constants. Solving linear equations involves finding the value of the variable that makes the equation true.

Categorizing Linear Equations
Isolating the Variable
Isolating the variable is a key step in solving equations, where the goal is to get the variable on one side of the equation and all other terms on the opposite side. This often involves performing inverse operations, such as adding, subtracting, multiplying, or dividing both sides of the equation to maintain equality.

Balancing Equations
Balancing equations is the principle that states that both sides of an equation must remain equal after performing the same operation on both sides. This is crucial in solving equations, as it ensures that any manipulation does not change the equality, allowing for the correct solution to be found.
