(please show your solution if possible & pls just type in the comments if unsure abt your answer.. thank you)

Multiply row 1 by .

Step-by-step explanation:

The augmented matrix of the system of linear equation is described below:

Where , if we need to create , we need to multiply row 1 by , that is to say:

Hence, the correct answer is: Multiply row 1 by .
