Homework 4, Problem 13
Use determinates to solve for x, y and z
4x – 3y+2z = 0
3x-4y-3z = -10
x+2y+z = -4
Det X =(-36 + 0 + -40) – (0 + -32 + -30) = -14
Det Y =(-36 + 0 + -20) - (0 + -24 + -40) = 8
Det Z = (64 + 0 + 30) - (0 + 36 + -60) = 110
Determinate = (-16 + 12 + -9) – ( -8 + 9 + -24) = 10
X = -14/10 = -1.4
Y = 8/10 = .8
Z = 110/10 = 11
