Here are the essential concepts you must grasp in order to answer the question correctly.
Augmented Matrix
An augmented matrix is a matrix that represents a system of linear equations. It combines the coefficients of the variables and the constants from the equations into a single matrix. For example, the system -3x + 5y = 2 and 6x + 2y = 7 can be represented as an augmented matrix by placing the coefficients of x and y in the first two columns and the constants in the last column.

Linear Equations
Linear equations are mathematical statements that express a relationship between variables using a linear function. They can be written in the form Ax + By = C, where A, B, and C are constants. Understanding how to manipulate and represent these equations is crucial for forming the corresponding augmented matrix and solving the system.

Row Operations
Row operations are techniques used to manipulate the rows of a matrix to simplify it, particularly in the context of solving systems of equations. The three primary row operations are swapping two rows, multiplying a row by a non-zero scalar, and adding or subtracting rows. These operations are essential for transforming the augmented matrix into a form that makes it easier to find solutions to the system.
