解方程组{4x=4y+8、3x=4y

方程组4=x+y,8=3x-y求x,y的解 解方程组24/(x+y) +24/(x-y) = 7/3 ,8/(x+y) +18/(x-y) = 4/3 解方程组 x-y/3-x+y/4=2 x-y/6-x+y/8=3 解方程组 4(x+y)-(2x-y)=14 ,3(x+y)-2(2x-y)=8 解方程组8/(x+y) +(x-y)/2=3,6/(x+y)-(x-y)/4=1 解方程组8y+5x=84y-3x=7 方程组 因式分解 4x^3-4x^2y-(x-y) 解方程组{4x+8(x+y)=480,4y+9(x+y)=480 解方程组：｛4x+5(x-y)=30,4y-3(x-y)=6 解方程组｛ 3x-4y(x-y)=3 { 2x-3y=1 方程组x-2y=8,3x-4y=5,x=?,y=? 解方程组x+y/3=x-y/4 2x+3y=11 解方程组3x+5(x+y)=2 3y-2(x+y)=4 解方程组,x+y/2=3x-2y=10+6x+y/4, 9y=3x-(x-1),4(x+y)-(x+4)=8y解方程组 3(x+y)-2(x-y)=4; 3(x+y)+2x-2y=8 3(x+y)-2(x-y)=4; 3(x+y)+2x-2y=8 解方程组 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2(x-y)/3-x+y/4=-1 6(x-y)-4(2x-y)=16 解方程组3(x+y)-4(x-y)=4和(x+y)/2+(x-y)/6=1kkkkkkkk
