tim x, y thuoc z biet :
/ x-y / + / y-z/ + /z - x / = 2015
tim x,y biet x,y thuoc z voi x,y cung dau x+y+|y|=2015
Tim x, y thuoc Z biet : | x-2| + (x-y+1)^2 =0
tim x, y, z thuoc Z sao cho /x-y/+/y-z/+/x-z/=2019
tim x, y thuoc Z:
2/x=y/3
tim x,y,z thuoc N sao cho 1/x+1/y+1/z=1/2
Tim x,y thuoc Z biet
x^2=I5+y^2
tim x,y thuoc z biet
-24/-6 = x/3 = 4/y^2 = z^3/-2
Tìm x;y;z;biết
x-y+2013:y-z=-2014:z+x=2015
