Timx,y biet x.3=y.4 va x-y=5
a) tim so nguyen x sao cho : 4x+5 chia het cho 2x-1
b) tim so nguyen x va y biet : xy+3x-2y -11 = 0
giup mik nha ! ai nhanh nhat mik tick cho !
tim cac so nguyen x y biet
(x + 2)(2y + 3)=6
Tim cac so nguyen duong x;y biet: |x-2y+1|.|x+4y+3|=20
tim cac so nguyen duong x;y biet |x-2y +1|.|x+4y+3| =20
Tim cac so nguyen duong x,y biet |x-2y+1|.|x+4y+3| = 20
tim cac so nguyen duong x,y biet |x-2y+1| |x+4y+3|=20
tim cac so nguyen x , y biet
e) (x - 3) (x + y)=-11
f)xy + 3x - 2y - 6 = 5
timx,y biet
x+1=y.(x-2)
