We can use Gaussian elimination to solve a system of equations. Row operations are performed on matrices to obtain row-echelon form. To solve a system of equations, write it in augmented matrix form. Perform row operations to obtain row-echelon form. Back-substitute to find the solutions. A...
Use Gaussian elimination to solve a systems of equations represented as an augmented matrix. Interpret the solution to a system of equations represented as an augmented matrix.We have seen how to write a system of equations with an augmented matrix and then how to use row operations and back-...
To solve a system by elimination, add or subtract the equations of the system in order to "eliminate" one of the variables. Continue this process until only one variable is known. Then, substitute this known variable into the preceding equations to find the remaining variables. What is the ...
