6.4 The number of equations is 6, and the number of variables is 8. Thus an undetermined system can be written as: x 1 + x 2+ x 3+ x 4+ x 5+ 3x 6+ x 7+ x 8 =10 2x 1 + x 2+ 5x 3+ 6x 4+ 6x 5+ 7x 6+ x 7+ 9x 8 =15 x 1 + 13x 2+ 14x 3+ 5x 4+ 6x 5+ 4x 6+ 9x 7 =13 9x 1 + 6x 2+ x 3+ x 4+ x 5+ 32x 6+ 5x 7+ 3x 8 =40 x 1 + 4x 3+ 5x 4+ 6x 5+ 8x 6+ 4x 7+ 7x 8 =8 10x 1 + 11x 3+ 4x 4+ 2x 5+ 3x 6+ 2x 7+ 8x 8 =0
