You are given 4 matrices below, each with one or more variables in lieu of a numerical element. Work offline to solve for each variable\'s value(s) that will make its matrix\'s determinant equal to zero (and, thereby, non-invertible). Type in the value(s) along the right column as indicated; report all solutions to one decimal place. Quiz points as defined. [5 4 -7 w] w = [2 4 -7 x] x = [5 -3 2 y 4 y 1 9 6] y = [180 h h 125] h =

Solution

2 ) Given matrix

2 4

-7 x

Given that

Determinant of given matrix = 0

Determinant of matrix = 2x - (-28)

2x - ( -28 ) =0

2x + 28 =0

2x = -28

x = -14

Therefore,

x = -14
