(10x+y)-(10y+x)化简(10x+y)-(10y+x)化简(10x+y)-(10y+x)化简(10x+y)-(10y+x)=10x+y-10y-x=9x-9y=10x+y-10y-x=9x-
(10x+y)-(10y+x)化简
(10x+y)-(10y+x)化简
(10x+y)-(10y+x)化简
(10x+y)-(10y+x)=10x+y-10y-x=9x-9y
=10x+y-10y-x
=9x-9y
(10x+y)-(10y+x)=10x+y-10y-x =(10x-x)+(10y-y)=9x+9y
化简
(10x+y)-(10y+x)化简
化简:3(x+y)+5=10y+x
(x-y)^2+10(y-x)+25因式分解 (x-y)²-10(y-x)+25(x-y)²+10(y-x)+25只要结果
若x-y不等于0,2x-3y=0,则分式(10x-11y)/(x-y)的值是()?(10x-11y)/(x-y) =[(8x-8y)+(2x-3y)]/(x-y) =8为什么8X-8Y=8?(10x-11y)/(x-y)=[(8x-8y)+(2x-3y)]/(x-y)=8+(2x-3y)]/(x-y)=8+0=8
化简 2x-[3y-5x-(-2x-7y)]等于 ( ) A:-7x+10y B:5x+4y C:-x-4y D:9x-10y
化简 (x+2)平方-(x-y)(y-x)是(x+y)平方-(x-y)(y-x)
(10x+y)-(10y+x)=27
(y-x)²-10x+10y+25因式分解,
(x+y)²+10(x+y)+25
计算(x+y)^2+10(y-x)+25
(x+y)^2+10(x+y)+25
因式分解:25(x-y)²+10(y-x)+1
(x+y)平方-10(x+y)+25
(x-y)(x-y-3)-10因式分解
已知x²-y²=10,求[(x+y)³-2y(x+y)²-4(x+y)]÷(x+y)的值
(x+y)(x+y+10)+25=0 x-y=3.求x,y的值(x+y)(x+y-10)+25=0 x-y=3.求x,y的值
1.5(x+y)+3(x-y)=27(x+y)-3(x-y)=-62.x-y/7 - x+y/10 =1/22(x-y)-5(x+y)=3所谓细节决定成败,
化简 x-y+(2y²)/(x+y)
