-6x+38y--34
Solve the system by completing the steps below to produce a reduced row-echelon form. R₁ and R₂ denote the first and second rows, respectively. The arrow
notation () means the expression/matrix on the left becomes the expression/matrix on the right once the row operations are performed.
(a) For each step below, enter the coefficient for the row operation. The
first matrix in Step 1 is the augmented matrix for the given system of
equations.
