方程组 (3/X+Y)+2/(X-Y)=6 3(X+Y)-2(X-Y)=28
求x+y/3+x-y/2=6 3(x+y)-2(x-y)=28方程组的解
解下面方程组,x+y/3+x-y/2=6 3(x+y)-2(x-y)=28,
3/x+y+2/x-y=6,3(x+y)-2(x-y)=28解这个方程组
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
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
x+y/2+x-y/3=6,4(x+y)-5(x-y)=2用加减消元法解方程组
用换元法解方程组 2分之x+y+3分之x-y=6 2(x+y)+(x-y)=12
解方程组 {(x+y)/2+(x-y)/3=6 5(x+y)-2(x-y)=4
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]-5[X-Y]=2
