1. 2x + y = 26
y + 3z = 20
3x – 2z = 19
2. x + y + z = 16
4z – 31 = x
3z – 17 = y
3. 3x – 2y = 1
4x – 5z = 11
3y + 4z = –18
4. x + y + z = 16
x + z = 11
y + z = 13
5.x + y + z = 9
x–1=y
x–2=z
6. 2x + 3y = 3
3x – 4z = –8
y+z=3
7. 6x – 10y + 2z = 4
–x – 7y + 2z = –7
3x – 5y + 6z = 7
8.2x – y – z =
2x – 6y – 2z = 3
x+ y+z=
