xy + x - 2y = 5
Tim nghiem nguyen duong cua pt:\(\frac{xy}{z}+\frac{yz}{x}+\frac{zx}{y}=3\)
tim gia tri nguyen cua m de hpt
\(3x-y=2m-1 va x+2y=3m-2\)
co nghiem (x;y) tm x^2 + 2y^2 = 9
Tim nghiem nguyen cua phuong trinh x^2 - xy + y^2 - 4 = 0
Ai giải dc cảm ơn
tim nghiem nguyen duong cua phuong trinh xy^2+2xy+x = 32y
a,giai pt (x-3/x-2)^3-(x-3)^3=16
b,tim nghiem nguyen cua pt: 8x^2+23y^2+16x-44y-1180=0
tim nghiem nguyen duong: \(3^x=y^2+2y\)
tim nghiem cua pt :\(x^2-xy-2015x+2016y-2017=0\)
