若方程组2X+3Y=K+4(1)X-Y=3K-3(2)的解满足X-Y= 5,求K的值
要详细一点的过程啊,谢谢了!答对追加悬赏分落!~~
对不起，是X+Y=5

解答
x-y=5可以得出x=y+5带到二式中得k=8/3
推荐
- 若方程组{2X+3Y=K+4 X-Y=3K-3的解满足X+Y=5,求K的值
- 1、若关于x,y的方程组{x+y=3k,x-y=7k的解满足方程2x+3y=6,求k的值 2、对于x,y
- 解方程组y+x=5 2x+y=k 2x+3y=3k-4
- 如果方程组｛2x+3y=k-1；3x+2y=3k+1的解满足x>y,则k为多少?
- 1.如果方程组2x+3y=k-1,3x+2y=3k+1的解x、y,满足x>0,y
