The solution set is:
( x, y, z) = (1, 1, 1)
Solution:
it is on the picture I uploaded, I used Gaussian Elimination Method then I solve.
Check:
3(1) + 2(1) = 5
3 + 2 = 5
5 = 5
2(1) + 3(1) = 5
2 + 3 = 5
5 = 5
1 + 3(1) - 1 = 3
1 + 3 - 1 = 3
4 - 1 = 3
3 = 3
So, definitely, the values of x, y, and z are all 1.
