解方程组2x-3y=2 x+2y=-3
解方程组{ 3x-4y(x-y)=3 { 2x-3y=1
解方程组X+Y/2=3X-2Y=10+6X+Y/4
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/3=x-y/4 2x+3y=11
用代入法解方程组:y=3(x-y),x=2(x-y)
解方程组:解方程组:|X+Y|=1|X|+2|Y|=3
解方程组:(x+3)(y-2)=(x-3)(y+10),(x+1)(y+3)=(x-2)(y+12)
求x+y/3+x-y/2=6 3(x+y)-2(x-y)=28方程组的解
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)=34(x+y)+3x=15+3y.
数学书解方程组{2(x+y)-(x-y)=3,(x+y)-2(x-y)=1
