Tim cac so nguyen x,y thoa man : xy+3x-y=8
tim so nguyen x, y thoa man : 3.x.y + x =2.y
tim so nguyen x, y thoa man : 3.x.y + x =2.y
tim so nguyen to x, y thoa man : 51.x +26.y= 2000
tim so nguyen x , y thoa man : x - 2.x.y + 3.y = 1
tim cac so nguyen to x,y thoa man 272x= 11^y + 29
tim cac so nguyen to x,y thoa man:(x -2) nhan (y-3)=-4
tim so nguyen to x, y thoa man 51x + 26y = 2000
tim cap so x;y thoa man:
x.y+y-3.x =13
nhanh giùm mình với nhớ viết cách làm nha
