解方程(x+1/3)(y+1/3)-xy=6.3解方程(x+1/3)(y+1/3)-xy=6.3解方程(x+1/3)(y+1/3)-xy=6.3(x+1/3)(y+1/3)-xy=6.3xy+(1/3
解方程(x+1/3)(y+1/3)-xy=6.3
解方程(x+1/3)(y+1/3)-xy=6.3
解方程(x+1/3)(y+1/3)-xy=6.3
(x+1/3)(y+1/3)-xy=6.3
xy+(1/3)x+(1/3)y+1/9-xy=6.3
1/3(x+y)+1/9=6.3
(x+y)=6.3*3-1/3=189/10-1/3=567/30-10/30=557/30
这个貌似不能给出具体的解,把前面的括号乘开。可得x+y=18.9
