Tim x , y , z biet: x /y+z+1 = y/ z+x+2 = z/ x+y−3 =x+y+z Cach lam ho minh voi
Tim x , y , z biet:
\(\frac{x}{y+z+1}=\frac{y}{z+x+2}=\frac{z}{x+y-3}=x+y+z\)
Cach lam ho minh voi
Tim x y z biet x/(y-z)=y/(x+z)=z/(y-x)=x-y+z
Tim x,y,z biet x-y+z=x/(y*z)=y/(z+x)=z/(y-x)
tim ;x;y;z
y{x+y+z}=18
x{x+y+z}=-12
z{x+y+z}=-3
gup mih nha??????
aj lam duoc bai nay minh cho tich nhaaaas?/////@@@
C1: tìm x và y biet 5/x + y/4 =1/8
C2: thay các chữ số thích hợp:
1 : 0,0abc = a+b+c+d
C3: tìm x,y,z biết
x/(y+z+1) = y/(x+z+1) = z/(x+y+2) = x+y+z
Giai cach lam nha
tim x,y,z biet; x/z+y+1=y/x+z+1=x+y-2=x+y+z
Tim x, y, z biet x, y, z > 0 , x-y/z = y-z/x = z-x/y va x+2y+3z=30
tim x;y;z biet x(x+y+z)=2; y(x+y+z)=25; z(x+y+z)=-2; x>0
