x+y=10,6x+4y=46
x+y=10,6x+4y=46
x+y=10,6x+4y=46
y=10-x
6x+4(10-x)=46
6x+40-4x=46
2x=46-40
x=3
y=10-3=7
x+y=10,6x+4y=46
x^2+4y^2-6x+4y+10=0,求x^4-y^4/(x+2y)(x-2y)*x+2y/xy^2+y^3除以(x^2+y^2/y)^2的值
(x+y)/6+(x-y)/10=1,(x+y)/6-(x-y)/10=5
{6/x+y+10/x-y=30 6/x+y-10/x-y=-1
{3(x+y)-4(x-y)=4 {x+y/2 + x-y/6=1
x+y/2+x-y/3=6,4(x+y)-3(x-y)=-20
{(x+y)/2+(x-y)/3=6 4(x+y)-3(x-y)=-20
4(x+y)-3(x-y)=-20,2/x+y+3/x-y=6
(x+y)/2- x-y/2=6 3(x+y)=4(x-y)
x+y/3+x-y/2=6 4(x+y)-2(x-y)=40
x,y 满足x(x-2)-y(y-6)=-10,求x,y的值
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。
2/x-y + 6/x+y = 11/10 分式方程组 4/x-y - 6/x+y =1/10
谁会解10x+y=6(x+y)+3 10y+x=4(x+y)+9
3(2X+Y)+(2(2x-Y)=6 (8X+4y)-(10X-5Y)=2
已知:4x^2+y^2-4x-6y+10=0,求y/x-x/y的值
解方程组,x+y/2=3x-2y=10+6x+y/4,
