解方程组:x+y/2+x-y/3=6,(x+y)+5(x-y)=38 谢.
解方程组,x+y/2=3x-2y=10+6x+y/4,
x+y+xy=5 (x^2)y+x(y^2)=6 解方程组
解方程组(x+y)(x-2y)=-5 (x-y)(x+2y)=7
解方程组 y=2x x+y=3
解方程组:3(x-5)=3y-6 x-y/3-x+2y/6=2解方程组:3(x-5)=3y-6 x-y/3-x+2y/6=2
解方程组 X+Y/2+X-Y/3=6 4[X+Y]-5[X-Y]=2
解方程组2(x-y)/3-x+y/4=-1 6(x-y)-4(2x-y)=16
解二元一次方程组{x+y/2+x-y/3=6,4(x+y)-2=5(x-y)
解方程组2分之x+y+3分之x-y=6 4(x+y)-5(x-y)=2
解方程组 {(x+y)/2+(x-y)/3=6 5(x+y)-2(x-y)=4
3/x+y+2/x-y=6,3(x+y)-2(x-y)=28解这个方程组
解方程组:2(x-y)/3-x+y/4=-1 ,6(x+y)-4(2x-y)=16
解方程组;x+y/2=x-y/3=6 4(x+y)-3(x-y)=-20
2(x+y)-3(x-y)=1 6(x+y)+7(x-y)=51 解方程组
解方程组﹛2(x+y)-3(x-y)=1 6(x+y)+7(x-y)=51
解二元一次方程组3(x+y)-4(x-y)=4 x+y/2+x-y/6=1
解方程组3(x+y)-4(x-y)=4和(x+y)/2+(x-y)/6=1kkkkkkkk
