Find the determinant of the coefficient matrix.

1.   9x - 7y = -101 8x - 5y = -80	2.   4x - 2y = -48 3x - 6y = -27	3.   -5x + 7y = -104 -9x - 6y = -57
4.   -4x + 8y - 3z = 130 9x - 4y - 7z = 13 -5x - 1y + 8z = -87	5.   6x - 3y + 2z = -75 -3x + 7y + 5z = -7 -6x - 1y - 2z = 55	6.   -4x - 9y - 8z = -46 -1x + 6y - 5z = -46 -7x + 9y - 2z = -58
7.   4x + 3y = -54 -7x + 2y = 80	8.   3x - 1y - 8z = 57 -5x - 4y - 6z = 112 -2x + 8y - 7z = 105	9.   -9x + 3y = 12 -1x + 6y = 75
10.   4x - 1y = -34 -9x - 6y = 126	11.   5x + 8y = -21 -3x + 2y = -1	12.   -6x - 3y - 1z = -17 -2x + 4y - 8z = -130 -5x - 9y + 7z = 124
