(x-5)(100-7(x-7))=y求化简(x-5)(100-7(x-7))=y求化简(x-5)(100-7(x-7))=y求化简(X-5)(100-7(X-7))=Y(X-5)(149-7X)=Y
(x-5)(100-7(x-7))=y 求化简
(x-5)(100-7(x-7))=y 求化简
(x-5)(100-7(x-7))=y 求化简
(X-5)(100-7(X-7))=Y
(X-5)(149-7X)=Y
184X-7X²-745=Y
5(x-y)³-3(x-y)²+7(x-y)-5(x-y)³+(x-y)²-5(x-y),其中,x-y=1/3.5(x-y)³-3(x-y)²+7(x-y)-5(x-y)³+(x-y)²-5(x-y),其中,x-y=1/3先化简,再求值;
-(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)
2(6X方+X)方-11(6X方+X)+5X四次方-10X方+9X三次方-7X方+12X(X+Y)方+2(X+Y)-15A四次方-21A方-100(X方+X)方-14(X方+X)+24X方(X-1)-Y方(X-1)
(x-y)^7除以(y-x)^5=?
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,
3(x-y)²-7(x-y)+8(x-y)²+5(x-y)
把x-y,合并同类项:5(x-y)+3(x-y)-7(x-y)=
把x-y看成一个整体,合并同类项:5(x-y)+3(x-y)-7(x-y)
已知5x-7y=0,求(x-y)/(x+y)的值
(x-4y)分之(3x)+(4y-x)分之(x+y)-(x-4y)分之(7y)
若(5x+y)/(7x+10y)=1/2则x/y=
7(x+y)^3-5(x+y)^2-2(x+y)十字相乘
因式分解:-x平方+4x-4;8(x平方-2y平方)-x(7x+y)+xy,4x三次方-4x平方y-(x-y),x平方y-5xy平方+6y三次方
[(x+2y)²-(x+y)(x-y)-7y²】÷(2y)
已知X=11Y,(X-2)*3=Y,(X-4)*5=Y,(X-6)*7=Y,(X-8)*9=Y ,求X、Y各是多少?
去括号并合并同类项(1)3x-2(x+7)+2(2x+5) (2)(4x-3y)-[-(3y-x)+(x-y)]-5x
化简求值(x+5y)(x+4y)-(x-y)(x+y),其中x=一又2/5,y=-1/7
先化简在求值 (x+5y)(x+4y)-(x-y)(x+y),其中,x=-2又2/3,y=3/7
