(x+500)*{(y+70)/100+1}=(x+1000)*(y/100+1)(x+500)*{(y+70)/100+1}=(x+1000)*(y/100+1)(x+500)*{(y+70)/10
(x+500)*{(y+70)/100+1} =(x+1000)*(y/100+1)
(x+500)*{(y+70)/100+1} =(x+1000)*(y/100+1)
(x+500)*{(y+70)/100+1} =(x+1000)*(y/100+1)
7X-50Y=15
帮我申请个q我告诉你
-{-[-(x-y)]}+{-[(x+Y)]}
(x+500)*{(y+70)/100+1} =(x+1000)*(y/100+1)
x(x-y)-y(y-x)+(x-y)²因式分解
{(x-y)²+(x+y)(x-y)}÷2x
(2x-y)乘(2x+y)+(2x-y)乘(y-4x)+2y(y-3x)
:x(x-y)-y(y-x) m(x-y)²-x+y
【x+y-(x÷y)²】³
x+1.3=y-1.2,x()y
化简((X-2Y)的平方+(X-Y)(x+Y)-2(X-3Y)(X-Y))除以Y
(x-y)(x-y)2(y-x) (x+2y-?)(x-2y+?)
X-[(X*30%+(X-20)*70%)]=X*6%Y/(1+6%Y) x是100 y是多少 还有这个是方程还是什么
把6x(x-y)的平方+3(y-x)的立方分解因式我知道答案是6x(x-y)^2+3(y-x)^3=6x(x-y)^2-3(x-y)^3=3(x-y)^2[2x-(x-y)]=3(x-y)^2(x+y)可为什么=6x(x-y)^2-3(x-y)^3=3(x-y)^2[2x-(x-y)]
计算:[(x/y-y/x)÷(x+y)+x(1/y-1/x)]÷y分之1+x
(x+y)(x+y)-4(x+y-1)
因式分解:3(x+y)(x-y)-(x-y)²
2(x-y)² -(2x-y)(-y+2x).求计算.
因式分解x²(x-2y)+y²(2y-x)
x(x+y)-y(3x-4y)因式分解.快.
