The required matrix is:
Step-by-step explanation:
We need to apply elementary row operation -2R₂+3R₁ tothe matrix:
Multiplying Row 2 with -2 and Row1 with 3 and adding,
-9 15 6
-16 2 -6
----------
-25 17 0
After applying this operation, Row 1 will be changed while Row 2 will remain same because we get -2R₂+3R₁ -> R₁
