-(-5x+y)-3(2x-3y)去括号再合并同类项求解如题啦
-(-5x+y)-3(2x-3y)去括号再合并同类项求解
如题啦
-(-5x+y)-3(2x-3y)去括号再合并同类项求解如题啦
-(-5x+y)-3(2x-3y)
=5x-y-6x+9y
= - x+8y
(2x-3y)-(5x-y)去括号
(2x+3y)-(5x-y)去括号
3x-【(y-x)-2x-y】 去括号,
整体去括号;化简[5(x-y)-3(x-y)-(x-y)+2(x-y)]-2(x-y)
整体去括号;[5(x-y)-3(x-y)-(x-y)+2(x-y)]-2(x-y)化简
去括号3(x-y)-2(2x-y)=
3x-2y-[-4x+(x+3y)]+y 去括号然后合并同类项,
去括号(4x-3y)-[-(3-x)+(x-y)]-5x 还是去括号4xy²-3x²y-{3x²+xy²-[2xy²-4x²y+(x²y-2xy²)]}
-(-5x+y)-3(2x-3y)去括号再合并同类项求解如题啦
5(2x-7y)-3(4x-10y) 去括号,再合并同类项,
去括号 5(2x-7y)-3(4x-10y)
(3+x)(3+y)去括号
x+(-y+3) x-(-3-y) -(x-y)+3 3-(X+Y) 怎样去括号?快
3(x+y)平方怎么去括号
3(x-y)平方怎么去括号
—[—(3x-y)]去括号.
—[—(3x-y)]去括号.
去括号x-3(y-1)
