方程组：4x-4y=32 x^2-y^2

解方程组,x+y/2=3x-2y=10+6x+y/4, 解方程组3x+5(x+y)=2 3y-2(x+y)=4 方程组x-2y=8,3x-4y=5,x=?,y=? 方程组4x+y=3 3x+2y=5,则x-y= 解方程组｛ 3x-4y(x-y)=3 { 2x-3y=1 解方程组x+y/3=x-y/4 2x+3y=11 由y=x²-4,y=2x-1联立方程组,求x,y. 已知方程组{3x+4y=10 4x+3y=-2,不解方程组则x+y= 解方程组x^2-y^2=x+y 4x^2-y^2+2x-y=0过程 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 解方程组 4(x+y)-(2x-y)=14 ,3(x+y)-2(2x-y)=8 二元一次方程组(x+y)/2+(x-y)/2=6,4(x+y)-5(x-y)=2 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
