Suppose that you are solving a system of 4 linear equations in 4 variables by the Gauss-Jordan method. If you use the transformation $10 R _ { 2 } + R _ { 3 }$ , which row or rows of the augmented matrix, if any, will change?
A) Rows 2 and 3
B) Row 3
C) Row 2
D) None

The transformation $10 R_2 + R_3$ means that you are adding 10 times the second row to the third row. This operation will only change the third row, leaving all other rows, including the second row, unchanged.
