-10y=39+3y y=?

y=(y')^3+y' -10y=39+3y y=? 10y+7=22y-11-3y 方程y''-3y'-10y=0的通解 10y+7=22y-5-3y 10y+7=22y-5-3y (y^2)^4y-(-2y)^3y^6= 数学题=y(y+3)-4(y+3)2=(y+3)(y-4y-12) y[y-3(x-y)]+y[3y-(y-3x)]=? y(y-2)²-y(y+3)(y-5) y=1/2 化简求值 y(y-2)²-y(y+3)(y-5) y=1/2 化简求值 y(y-2)²-y(y+3)(y-5) y=1/2 化简求值 y-12/y=? (x+y)(x+y-10)+25=0,且x-y=3,求x,y (x+y)(x+y-10)+25=0,且x-y=3,求x,y 10y+7=22y-5-3y y=? 10y+2(7y-2)=5(4y+3)+3y怎么算 10y-2(7y-2)=5(4y+5)-3y 3y-2（10-y)=4y-5(8-y)
