http://www.cs.bme.hu/~panahi/Anton.pdf WebRepresenting a linear system with matrices. A system of equations can be represented by an augmented matrix. In an augmented matrix, each row represents one equation in the system and each column represents a variable or the constant terms. In this way, we can see that augmented matrices are a shorthand way of writing systems of equations. WebStep 3. Repeat Step 2 using two other equations and eliminate the same variable as in Step 2. Step 4. The two new equations form a system of two equations with two variables. … in which career field would a mechanic be
