Question

Exercise 3(g)
Examine whether the following systems of equations are consistent or inconsistent and if
consistent find the complete solutions.
1. x + y + z = 4
2.
x + y + z = 6
2x + 5y – 2z = 3
x-y+z=2
x+7y - 7z = 5
2x – y + 3z = 9
3. x+y+z=1
4.
x + y + z = 9
2x + y + z = 2
2x + 5y + 7z = 52
x+2y + 2z = 1
2x + y - z = 0
5. x+y+z=6
6.
x-3y-8z = -10
x + 2 y + 3z = 10
3x + y - 4z = 0
x+2y + 4z = 1
2x + 5y +6z =13
7. 2x + 3y +z = 9
8.
x + y + 4z = 6
x+2y+3z = 6
3x + 2 y – 2z = 9
3x + y + 2z = 8
5x + y + 2z =13​
