2(10-0.5y)=-(1.5y+2)

2(10-0.5y)=一(1.5y十2) 解方程 2(10-0.5y)=-(1.5y+2) 2×(10-0.5y)=-(1.5y+2) 2(10-0.5y)=-(1.5y+2)要过程 2(10-0.5y)=-(1.5y+2) 一元一次方程,急,2(10-0.5y)=-(1.5y+2) x-y/x-x+y/y-(x+y)(x-y)/y² y/x=2 y''+2y'+10y=0微分方程的通解 yy''-(y')^2=y^2y' yy''-(y')^2=y^2y' y+y'-2y=2x 微分方程y - 2y' + y = x 2y''+y'-y=0 2y-2.4=0.5y-0.6 10+5y+y^2=0 6y^2-11y-10=( ? )(?) 解方程：2(10-5y)=-(1.5y+2) 计算 (y-0.3)/2=(0.7y+0.5)/0.5-1.5应该是(y-0.3)/0.2=(0.7y+0.5)/0.5-1.5
