Consider the following system of linear equations. 2x+ 10y=4 8x+45y=31 Solve the system by completing the steps below to produce a reduced row-echelon form. R, and R, 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.

Consider the following system of linear equations.
2x+ 10y=4
8x+45y=31
Solve the system by completing the steps below to produce a reduced row-echelon form. R, and R, 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.
