tim x va y thuoc z
a,3x - xy + 6y = 4
b,x^2 - 3xy + 2x - 6y = 7
tim x , y thuoc Z biet
a , 3x-xy+6y=4
b,x^2-3xy=2x-6y=7
tim x;y^2x-(6y)^2=1
Tim STN x, y sao cho x.2 - 6y.2 = 1
tim so nguyen to x y sao cho x^2-6y^2=1
tim cac so nguyen x,y biet:
2xy-6y+x=9
Tim x
|x+1|.(x-2)=2
5x+6y=48
|x|+3.|y|=4
tim snt x va y sao cho : x2 - 2x +1 = 6y2-2x + 2
a)A=X2 + 2022
b)B=(X+3)2 -11
c)C=X2 +(Y+1)4+5
d)D=(5-X)2+(X+Y+1)2 -10
