如果2x-3y=11-4m和x+3y=20-7m的x、y也满足3x+2y=21-5m,那么m的值是?

已知满足2x-3y=11-4m和3x+2y=21-5m的x、y也满足x+3y=20-7m，则m的值为 ___ ． （初一二元一次方程问题）已知满足2x-3y=11-4m和3x+2y=21+5m的x、y,也满足x+3y=10+7m,求m 已知方程组5x-y=m-2 ,x 3y=m 2的解也满足X-Y=2M-7,求M的值 已知x,y,m同时满足2x-3y=11-4m,3x+2y=21-5m,x+3y=20-7m,求m的值 已知满足x-2y=m-4和3x+2y=3m的x,y也满足x+4y=2m+3,那么m= 已知X、Y满足2X-7Y=3M,X+2Y=4m+5,且X+Y=0,求M的值 已知x,y满足2x-7y=3m,x+2y=4m+5,且x+y=o,求m的值 已知x-2y=m-4和3x+2y=3m的x,y也满足x+4Y=2m+3,那么m=多少 已知关于x,y的方程组2x-3y=11-4m/3x+2y=21-5m的解满足方程x+3y=20-7m,求m的值.求具体解 已知关于x,y的方程组2x-3y=11-4m/3x+2y=21-5m的解满足方程x+3y=20-7m,求m的值. 已知x.y满足2x-y=3m,x+2y=4m+5,且x+y=0,求m的值 已知x,y满足2x-y=3m,x+2y=4m+5,且x+y=0,求m的值
