8x - 19 = 3x + 1 5x -19 = 1 5x = 20 x = 4
168x3 - 45x2 + 3x = 3x(56x2 - 15x + 1) = 3x(7x - 1)(8x - 1)
(x + 1)(3x + 5)
8x + x = 1 -8x + 3x = -3 Clean up 9x = 1 -5x = -3 x = 1/9 x = 3/5 Two different answers. If you were expected to solve them simultaneously, this would be an incompatible set, returning an answer of {Φ} ■

= (3x + 5)(x + 1) so x = -5/3 or -1
8x-4 = -7+5x 8x-5x = -7+4 3x = -3 x = -1
