2(x+y)-3分之2(x-y)-3(x+y)+3分之2(x-y)化简全部过程!

2分之x+y+3分之x-y;4(x+y)-(x-y)谢谢了, 计算 x-2分之x方+1-2-x分之3-4x (x+y)x方-y方分之x方+y-x分之y方 x+y分之x-y=-2,求3(x+y)分之x-y减去x-y分之2(x+y)的值 若x-y分之x+y=3,求式子x+y分之5(x-y)—2(x-y)分之x+y的值 计算[3x分之2-(x+y分之2)乘以[3x分之x+(y-x^2-xy)]除以x分之x-y -(5x+y)-7(x-y) -2分之1(x+y)+4分之1(x+2y) 4x-2(x-2) -2x-(3x-1) x-(5x-2y)+2(2x-y) 计算(3y)分之2x+(3y)分之5x(3y)分之2x+(3y)分之5x(x+y)分之2y-(y+x)分之y-x(x²+3x)分之x²+9x+(x²+6x+9)分之x²-9 化简求值:已知【3x分之2-x+y分之2(3x分之x+y-x-y)】÷5x+3y=0 1.计算①(x-1-x+1分之8)×x+3分之x+1;②x+3y分之x-y÷x²+6xy+9y²分之x²-y²-x+y分之2y;③(x-x+1分之2x)÷x²-1分之x²-2x+1④(x²-2x分之x+2-x²-4x+4分之x-1)÷x³-2x²分之x-4 已知2x-y+1的绝对值+ (3x+2分之3y)平方=0,求代数式x+y分之y的平方除以(x-y分之x-1)(x-x-y分之x平方 填空:1、x+3分之2x=()分之2x²;2、(x+y)²分之x²-y²=()分之x-y 2x-3分之x+()=2x-3分之1x-2y分之x的平方-()=x-2y分之4y的平方 y-x分之2x-3y-x-y分之x+2y 2x-3y分之y-x-x+2y分之x-y (x-4y)分之(3x)+(4y-x)分之(x+y)-(x-4y)分之(7y) (2x-y)²-4(x-y)(x+2y) 4(-2分之3x-3y)(2分之3x-3y) 2(x+y)-3分之2(x-y)-3(x+y)+3分之2(x-y)化简 其中x=-2,y=1 (1)ac分之2bc (2)xy²分之(x+y)y (3)(x+y)^2/x^2+xy (4)(x-y)^2/x^2-y^2
