5/10y还能化简吗
7y-10y+5=4y-5
8y+12=8-8y-5y+10
(5-2y)(4y的二次+25+10y)
10y+7=22y-5-3y 10y+7=22y-5-3y
10+5y+y^2=0
(x+y)/6+(x-y)/10=1,(x+y)/6-(x-y)/10=5
10y-2(7y-2)=5(4y+5)-3y
3-5-2y/5=y-4-7y/10+y+2/2
10y+2(7y-2)=5(4y+3)+3y怎么算
(x+5y)^+(2x+10y)(3x-y)+(3x-y)^
(x+5y)²-(2x+10y)(3x-y)+(3x-y)²
3y-2(10-y)=4y-5(8-y)
10y+7=22y-5-3y y=?
10y+2=22y-5-3y,Y等于几,解一元一次方程
5x^3y(x-y)^3-10x^4y^3(y-x)^2因式分解
5x^3y(x-y)^3-10x^4y^3(y-x)^2
5X^3Y(X-Y)-10X^4Y^3(Y-X)^2因式分解
