方程组-3x+y=6,-2x+y=-4的解是,则一次函数y=3x+6与y=2x-4的交点坐标是

一道很简单的方程组3（x+y）-4(x-y)=4(x+y)/2+(x-y)/6=1是方程组啊. 解方程组,x+y/2=3x-2y=10+6x+y/4, 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+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 用代入法解此方程组：（x+y)/2+(x-y)/3=6 4(x+y)-5(x-y)=2求方程组的正整数解：x+y+z=7 2x+3y+4z=20 2X-3Y=6 3X+4Y=6的方程组的解 x/2-y/3=0x/4+y/6=2的方程组的解 解方程组;x+y/2=x-y/3=6 4(x+y)-3(x-y)=-20 解方程组2(x-y)/3-x+y/4=-1 6(x-y)-4(2x-y)=16 解方程组：2(x-y)/3-x+y/4=-1 ,6(x+y)-4(2x-y)=16 2元一次方程组 2/x+y+3/x-y=6 4(x+y)-3(x-y)=-20 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 3(x+y)—4(x-y)=4,(x+y/2)+(x-y/6)=1.解方程组 解方程组3(x+y)-4(x-y)=4,x+y除以2+x-y除以6=1 一道二元一次方程组!3(x+y)-4(x-y)=4,(x+y)/2+(x-y)/6=1 解方程组⑴(x+y)/2-(x-y)/3=6,⑵3(x+y)=4(x-y) 解方程组 x-y/3-x+y/4=2 x-y/6-x+y/8=3
