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 duong(x,y) de gia tri truyet doi cua x-2y+1 * gia tri tuyet doi cua x+4y+3 =20
Tim cap so x;y nguyen duong biet :
/ x - 2y + 1/ . /x + 4y + 3/ = 20
lam nhanh cho minh nhe cac ban , thanks
Tim cac so nguyen x va y, biet rang:
a) (x-2)(2y+1)=8; b) (8-x)(4y+1)=20
giup mk nha cac bn
a, Tim cac so nguyen duong x,y nho hon 10 sao cho 3x - 4y = -21
b, tim cac so nguen x,y sao cho xy -2x + 5y -12 = 0
1. tim cac cap so nguyen duong (x, y) sao cho:
2 x3 + xy = 11
2. tim cac cap so nguyen duong (x, y, z)sao cho:
x + y + z = x*y*z
3. tim x thuoc z, biet;
|x| = -2003
|x| = |-2003|
minh dang can gap lam. chieu mai phai nop rui
