2Y/4+1+10Y/6+1=1-1-2Y/3 怎么解呀

2Y/4+1+10Y/6+1=1-1-2Y/3
2y/4+10y/6+2y/3=-2
6y+20y+8y=-24
34y=-24
y=17/12

2Y/4+1+10Y/6+1=1-1-2Y/3 1/4(x+y)+1/2(x+y)*(x+y)>=x*根号y+y*根号x 1/3[3y-(10-7y/2)]-1/6[2y-(2y+2/3)]=y/2-1 (4/y^2)+y^2=5,y=? 已知X+Y=-4，求1/2（X+Y)+4(X-Y)-3(X-Y)-3/2(X+Y)-X+Y 4y*-2y+4/1=0 求1/4(x+y)+1/2(x+y)*(x+y)的最值 (x+2y)(x+y)=4XX-5xy-6yy 求x/y 已知：4x^2+y^2-4x-6y+10=0,求y/x-x/y的值 (y^2/y-2)-(4/y-2)=y-2对吗
