(6x-12)/x=(6y+12)/(y+5) (6x+16)/(x+5)=(6y-16)/y x=?y=?
(6x-12)/x=(6y+12)/(y+5) (6x+16)/(x+5)=(6y-16)/y x=?y=?
第一条式子化简:6-12/x=6-18/(y+5) ,12y+60=18x
第二条式子化简:6-14/(x+5)=6-16/y ,14y=16x+80
结果:x=30,y=40
就是这样了(*^__^*)
[12(x+y)^3+3(x+y)(x-y)^2]÷6(x+y)
|x|+y=12 |y|+x=6怎么解
12X+6Y=72 x、y是 多少?
8x-8y-3x-3y=-12,6x+6y-8x+4y=16
填空题 x+y/4=x-y/6=3x+12y+5/8 x= y=
解方程 x(x+y+z)=6 y(x+y+z)=12 z(x+y+z)=18
解方程组{x(x+y+z)=6,y(x+y+z)=12,z(x+y+z)=18
用换元法解方程组 2分之x+y+3分之x-y=6 2(x+y)+(x-y)=12
用换元法解方程组 2分之x+y+3分之x-y=6 2(x+y)+(x-y)=12
解方程组:x+y/2+x-y/3=6 4(x+y)-5(x-y)=12
解方程组{2(x-y)/3 - x+y/4=-1 6(x+y)-41(x-y)=12
8(x-y)=3(x+y)-12 6(x+y)=4(2x-y)+16
8(x-y)=3(x+y)-12 6(x+y)=4(2x-y)+16
已知x^2-y^2=12,x+y=6,求x^y-y^x的值.
[12(x+y)的立方+3(x+y)(x-y)的平方]÷6(x+y)=
X+Y=12,X和Y( )比例;6分之X和Y分之5,X和Y( )比例
如果|x+y+z-6|+|2x+3y-z-12|+|2x-y-z|=0求x,y,
2(x-2y)²-7(x-2y)³+3(2y-x)²+(2y-x)³合并同类项 这个式子2(x-2y)²-7(x-2y)³+3(2y-x)²-(2y-x)³=2(x-2y)²-7(x-2y)³+3(x-2y)²+(x-2y)³=5(x-2y)²-6(x-2y)³=(x-2y)²(5-6x+12y)
