Answer:
Step-by-step explanation:
8x + 12y – 2z = -36
-5x + 3y + 2z= 15
3x + 15y = -21
3x + 2y – 4z = -24
-10x + 6y + 4z = 30
-7x + 8y = 6
3x + 15y = -21
-21x + 24y = 18
21x + 105y = -147
129y = -129
y = -1
3x – 15 = -21
3x = -6
x = -2
-8 – 6 – z = -18
-14 – z = -18
-z = -4
z = 4
x = -2, y = -1, z = 4
