bai 1 tim cac so nguyen x,y biet
a,x/3=7/y b,x/y=-3/11 c,x/y-1=5/-19
bai 2 tim cac so nguyen x,y,z,t biet
12/-6=x/5=-y/3=z/-17=-t/-9
Tìm các số nguyen x,y thỏa mãn 2xy+x+y
Đúp mình cần gấp
tim so nguyen x, y thoa man 3x - 13 = y(9x-13)
Tim cac cap so nguyen x,y biet
a,xy=-5
b,(x+2)(2y-3)=8
c,(x-2)^2+(2x-y)^4=0
d,|x|+|y|=1
e,|2x+1|+|y|=4
f,|x-13|+|2y-8|<hoac= 0
g,|x-5|+|y+2|=2
h,|x+3|+|2y+1|=3
Tim so nguyen x,y
(3x-1).(x+5)=13
xy-3y+y=-4
xy=2(x+2)
MONG CÁC BẠN GIẢI GIÚP MÌNH BÀI TOÁN NÀY.CẢM ƠN !
Tim so nguyen x , y, z , t biet : 38 * ( x * y * z * t + x * y + x * t + z * t + 1 ) = 49 * ( y * z * t + y +t )
Tim cac cap so nguyen x;y biet : (2x-1)*(y-4)=-13
Tim cac so nguyen x,y
A,x/4=y/7 va x-y=9. B,x/2=y/5 va 3x-y=5
Cho x;y la so nguyen sao cho | x | + | y | = 5. So cap so nguyen ( x;y ) thoa man la
