已知x/(y+z+t)=y/(x+z+t)=z/(x+y+t)=t/(x+y+z) 求a=(x+y)/(z+t)+(y+z)/(z+t)+(x+z)/(y+t)+(x+t)/(y+z）整
已知x/(y+z+t)=y/(x+z+t)=z/(x+y+t)=t/(x+y+z) 求a=(x+y)/(z+t)+(y+z)/(z+t)+(x+z)/(y+t)+(x+t)/(y+z）整
已知x/(y+z+t)=y/(x+z+t)=z/(x+y+t)=t/(x+y+z) 求a=(x+y)/(z+t)+(y+z)/(z+t)+(x+z)/(y+t)+(x+t)/(y+z）整
x/(y+z+t)=y/(x+z+t)=z/(x+y+t)=t/(x+y+z) =k
x=k(y+z+t)
y=k(x+z+t)
z=k(x+y+t)
t=k(x+y+z)
x+y+z+t=3k(x+y+z+t) 得k=1/3 得 x=y=z=t
故所求值为4
已知x/(y+z+t)=y/(x+z+t)=z/(x+y+t)=t/(x+y+z) 求a=(x+y)/(z+t)+(y+z)/(z+t)+(x+z)/(y+t)+(x+t)/(y+z）整

已知x,y,z均为int型变量. x=y=z=-1; x++&&--y&&z--||--x; printf(x=%d y=%d z=%d
,x,y,z);_____请问一下这个题目的解题思路,运算顺序..在运算前一题的时候x=y=z=-1;++x&&++y&&++z;printf(x=%d y=%d z=%d
,x,y,z);我是
已知 x/(y+z)+y/(z+x)+z/(x+y)=1求 (x*x)/(y+z)+(y*y)/(x+z)+(z*z)/(x+y)=?
matlab中解方程组syms x y z t[x,y,z,t]=solve(2*x+3*y-z+t-2,5*x+y+z-t-13,x-y+2*z+2*t-3,3*x+2*y+2*z+9*t+3)结果:x =-2y =1z =2t =4结果是不对的.做了如下调整：syms x y z t[t,x,y,z]=solve(2*x+3*y-z+t-2,5*x+y+z-t-13,x-y+2*z+2*t-3,3*x+2*y+2
