方程组{3x+2y=10 x=6-2y 的解为-------------------.

解方程组,x+y/2=3x-2y=10+6x+y/4, 解方程组 y=2x x+y=3 解方程组 10（x-y)=3(x+y)+15 6(x+y)=4(2x-y)+1610（x-y)=3(x+y)+156(x+y)=4(2x-y)+16 解方程组 10（x-y)=3(x+y)+15 6(x+y)=4(2x-y)+1610（x-y)=3(x+y)+156(x+y)=4(2x-y)+16分开的。 已知方程组2x+3y=10,3x+2y=15,不解方程组则x+y=? 已知方程组{3x+4y=10 4x+3y=-2,不解方程组则x+y= 数学问题方程组3分之x+y+2分之x-y=6 3（x+y)-2(x-y)=28方程组3分之x+y+2分之x-y=63（x+y)-2(x-y)=28 已知方程组{2x+y=6,x-3y=1,不解方程组,求7y(x-3y)²-(3y-x)²的值.已知方程组{2x+y=6,{x-3y=1.不解方程组,求7y(x-3y)²-(3y-x)²的值.已知方程组{2x+y=6，{x-3y=1.不解方程组，求7y(x-3y)²-(3y-x)³ 2/x-y + 6/x+y = 11/10 分式方程组 4/x-y - 6/x+y =1/10 解方程组:(x+3)(y-2)=(x-3)(y+10),(x+1)(y+3)=(x-2)(y+12) 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 2元一次方程组 2/x+y+3/x-y=6 4(x+y)-3(x-y)=-20 方程组{x+y/3+x-y/2=6,3(x+y)-2(x-y)=28 方程组 (3/X+Y)+2/(X-Y)=6 3(X+Y)-2(X-Y)=28 解方程组;x+y/2=x-y/3=6 4(x+y)-3(x-y)=-20 解方程组 2x+y(y-2x)=9 (x+y)(x+y-3)=10十万火急!求解! 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
