(2, 3, 4)
(4, 3, –2)
(4, 3, 2)
(6, 7, –2)

Answer 1

I can’t see the image file (mc019-1.jpg). Please either paste the three equations here or re‑upload the image.

If you want to check the four given candidate solutions yourself, do this for each triple (x,y,z):

1. Substitute x, y, z into each equation of the system.
2. If all three equations are satisfied, that triple is a solution; if any equation fails, discard that triple.

If you paste the system here I’ll check the four choices (2,3,4), (4,3,−2), (4,3,2), (6,7,−2) and show the work.
