Question

Solve the system by Gauss - Jordan elimination.
{ 1/3 x + 3/4 y - 2/3 z = -8
x + 1/2 y + 1/3 z = 18
1/6 x = 1/8 y - z = -24


a. (−6, 8, −24)
b. (−6, −8, −24)
c. (0, 8, −24)
d. (6,8,24)
e. (6, −8, 24)

Answer 1

1/6 x = 1/8 y - z = -24

assume you mean

1/6 x + 1/8 y - z = -24

Answer 3

That comes out
4,34/3,26
so I think you gave me another typo.
