Answer:
The answer to your question is:
x = -8; y = 1 ; z = -4
Step-by-step explanation:
Δ =
= 40 + 24 + 18 - (-4 + 45 - 96)
= 82 + 55
= 137
Δx =
= - 480 - 144 - 156 - ( 24 - 540 + 832)
= -780 -316
= - 1096
Δy =
= 40 + 24 + 18 - ( - 4 + 45 - 96)
= 82 + 55
= 137
Δz =
= 1040 - 360 - 72 - ( - 104 - 180 + 1440)
= 608 - 1156
= -548
x = -1096/ 137 = -8
y = 137 / 137 = 1
z = -548 / 137 = -4
