Use the determinant feature of a graphing calculator to solve the system by Cramer's rule . (Round to one decimal place.)
-2.6x - 0.7y + 5.3z - 3.4w = 2.9 6.5y + 0.7w = -1.8
4.0z - 2.2w = 1.5
4.9x + 0.6w = 3.2
A) {(0.5, -0.4, 1.1, 1.3) }
B) {(0.5, 0.4, 1.1, -6.3) }
C) {(-0.5, -0.4, 1.1, 9.4) }
D) {(0.5, -0.4, -0.3, -1.3) }
