方程组{x=3y+2 x-6y=16}的解,
求x+y/3+x-y/2=6 3(x+y)-2(x-y)=28方程组的解
解方程组:2(x-y)/3-x+y/4=-1 ,6(x+y)-4(2x-y)=16
解方程组 10(x-y)=3(x+y)+15 6(x+y)=4(2x-y)+16
如果方程组3x+y=k x+3y=2的解x,y
解方程组:{x+|3x-y|+3y=15 2x+y=6
解方程组X+Y/2=3X-2Y=10+6X+Y/4
3/x+y+2/x-y=6,3(x+y)-2(x-y)=28解这个方程组
解二元一次方程组:{5(x+y)+3(x-y)=2{7(x+y)-3(x-y)=-6
解方程组 x-y/3-x+y/4=2 x-y/6-x+y/8=3
解方程组 {(x+y)/2+(x-y)/3=6 5(x+y)-2(x-y)=4
解方程组 X+Y/2+X-Y/3=6 4[X+Y]-5[X-Y]=2
2(x+y)-3(x-y)=1 6(x+y)+7(x-y)=51 解方程组
