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

The transformation $- 10 \mathrm { R } _ { 3 } + \mathrm { R } _ { 2 }$ specifically targets Row 2 by adding to it the result of multiplying Row 3 by -10. This operation does not alter Row 3 itself; it only changes Row 2 based on Row 3's values.

Provide an Appropriate Response −10R3+R2- 10 \mathrm { R } _ { 3 } + \mathrm { R } _ { 2 }−10R3​+R2​
