Which systems of linear equations have no solution? x + y + z = 1,100
x-2y - Z=-500
2x + 3y + 2z = 2,600

x + y + z = 1,500
X-y-z= -500
2x + y + z = 2,000

x + y + z = 1,400
x-2y - z= -500
2x + 2y + 2z = 2,700

x + y + z = 1,400
-0.5x – 0.5y - 0.5z = -900
2x + 3y + 2z = 3,000

x + y + z = 1,900
X- y - 2z = -2,000
2x + 2y + z = 1,100

x + y + z = 2,400
2x - 2y + 2z = 700
x + 3y + z = 2,400
