Question

Wilma performs the elementary row operation represented by 2R1 - R3 on matrix A.​

Answer 1

Answer:

[-8 1]

[ 0 4]

[ 6 3]

[ -3 -4]

Step-by-step explanation:

The given matrix is;

[-1 2]

[ 0 4]

[ 6 3]

[ -3 -4]

From the image given;

Row 1 is; (-1, 2)

Therefore, 2R1 = 2(-1, 2) = (-2, 4)

Row 3(R3) is; (6, 3)

Thus;

2R1 - R3 = (-2, 4) - (6, 3) = (-8, 1)

The new matrix after the transformation is;

[-8 1]

[ 0 4]

[ 6 3]

[-3 -4]
