Determine which of the folilowing systems of linear equations has a solution.
X1 + x2 - x, + 2x4 = 2
X1 + x2 + 2x3
2x1 + 2x2 + x, + 2x4 = 4
(b) x1 + x2 - X3 = 1
(2x1 + x2 + 3x3 = 2
(a)
(d) ( x1 + x2 + 3x3 - x4 =0
Xị + x2 + X, + x4 = 1
X1 - 2x2 + X3 - x4 = 1
4x1 + x2 + 8x, - x4 = 0
X1 + 2x2 + 3x, = 1
X1 + x2 - x3 = 0
x1 + 2x2 + x3 = 3
(c)
X1 + 2x, - x3 = 1
2x1 + x2 + 2x, = 3
X1 - 4x2 + 7x, = 4 .
