求所有满足方程组现在要放8个车,则所有放法种数为{‘不夕一z一x一y,2二之一y一x一z,夕之一x一y一z,的三元实数组(x,y,2). 解原方程组可化为{图2令m一(x+l)(y+1)一z+1,(x+1)(z十1)一y+1,(少+1)(z+l)=x+1.x+1,n~夕+1,t=z+1可得若m,n,t中有一个为O,则其余两个必为O,即(0,o,0)为新 For all the equations that satisfy the equation, we need to put 8 cars, and then all the species are set to be {’xixyz’ x’yy’, ’x2’,’y’x’z’, and ’xy’ -y’z’ Three-element real array (x, y, 2). The solution to the original system of equations can be changed to {Fig. 2 Let m - (x + l) (y + 1) - z + 1, (x + 1) (z - 1) One y+1, (less +1)(z+l)=x+1.x+1, n~xi +1, t=z+1 are available if m,n,t is O, then The other two must be O, that is, (0, o, 0) is new
