ta co : x . y = 2 . 3 = 6
vi 6 = 1.6= (-1).(-6)= 2.3= (-2).(-3)
\(\Rightarrow\)x = 1, y = 6
x = 6 , y = 1
x = - 1 , y = - 6
x = - 6 , y = - 1
x = 2 , y = 3
x = 3 , y = 2
x = -2 , y = -3
x = - 3 , y = - 2
tich minh nha ban oi , thanks
tim x,y thuoc z biet
-24/-6 = x/3 = 4/y^2 = z^3/-2
1 )Tim x, y thuoc Z
x + y = x.y
2) Tim x thuoc Z
(x + 1)+(x+3)+(x+5)+...+(x+99)=0(x-3)+(x-2)+(x-1)+...+10+11=11-12(x-5)+7(3-x)=530(x+2)-6(x-5)-24x=100tim x, y thuoc Z biet 3/x/ phan 2 +5/y/ phan 3=8
tim x, y thuoc Z biet : x.y - 2.x - 3.y = 5 ( trinh bay nha )
cac ban oi giup minh voi
1.tim a,b thuoc Z,biet:a.(2b-3)=-6
2.cho x,y thuoc Z thoa man x mu 2 +y mu 2 chia het cho 3.chung to x va y chia het cho 3.
tim x , y thuoc z : (x+3).(y-1)=3
x-1/9+1/3=1/y+2
x/2+y/3=x+y/2+3
Tim x;y thuoc z
Help me!
tim x,y thuoc Z biết (x-1)y=3
Tim x,y thuoc Z thoa:
x2 + (y-3)2 = 0
