The 2nd box that is correct is -1/2. I need to know how to solve the other two and what goes in the boxes. Show that the given matrices are row equivalent and find a sequence of elementary row operations that will convert A into .
=[124]
3,=[3-10]
1
=[124]
3→2-1×1[120]
1⁻¹ [-12-10]
1-2¹+-22[3-10]
1=
