Answer:

k = -3, g = 5

Step-by-step explanation:

I think the question is meant to be

The INVERSE of the left matrix is the right matrix.

Since the inverse of a 2 x 2 matrix P

a b

c d

is

(1/det(P)) times

d -b

-c a

we have

4 -5

1 -2

changed to

-2 5

-1 4

divided by the determinant of the left matrix

det() = (4*(-2) -1(-5)) = -8 - (-5) = -3 = k

g = 5 (the top right element of the inverted matrix)
