Tìm x ,y ,z biet :
a, |x+3/4|+|y-1/5|+|x+y+z|=0
b, |3x-4|+|3y-5|=0
c,|x+3/4|+|y-2/5|+|z+1/2| <0
d, |x+1/5|+|3-y|=0
tìm x,y,z biet:
x+1/2=y-2/-1=z+5/3 va x+2y+3z+28=0
giúp mình nha

giúp mình nha
tim x,y,z biet(x-1/5)^2020+(y+0.4)^2000+(z-3)^6=0
Tim x,y,z biet:
1)|x|+|1-x|+|x+2|=5
2)|x-1/2|+|y+2\3|+|x^2+xz|=0
tìm x y biet 2/3x=3/4y, 2y=1/5 z va x+y+z=1
Tìm X,Y,Z biet rang X.(X+Y+Z)=-5 ; Y(X+Y+Z)=9 ; Z(X+Y+Z) =5
Tim x, y, z biet
a ) |x-3,5|+ |x+5|=0
b) |x-1| + (y+1)^2 + |z-1|=0
c) ( x-1/3)^2 + (y-2)^2+ (z-1)^2 be hon hoac bang 0
d)(x-z)^2+ (y+x)^2 + (z+1/4)^2 =0
Cac ban giup minh voi minh can gap lam
