\(\left(x-y\right)+\left(y-z\right)+\left(x-t\right)+\left(t-x\right)=234567\)
\(x-y+y-z+x-t+t-x=234567\)
\(\left(y-y\right)+\left(t-t\right)+\left(x+x-x\right)-z=234567\)
\(x-z=234567\)
\(x=234567+z\)
vậy \(x=234567+z\)
x/y+z+t+2015 = y/x+z+t+2015 , y/x+z+t+2015 = z/x+y+t+2015 , z/x+y+t+2015 = t/x+y+z+2015 , t/x+y+z+2015 = 2015 /x+y+z+t*x+y/z+t+2015 + y+z/x+t+2015 + z+t/x+y+2015 + (t+2015) /x+y+z + 2015 +x /y+z+t
2x+y+z+t/x = x+2y+z+t/y = x+y+2z+t/z = x+y+z+2t/t

Tính P= x+y/z+t + y+z/t+x + z+t/x+y + t+x/z+y
Cho dãy tỉ số (2015*x+y+z+t)/x=(x+2015y+z+t)/y=(x+y+2015z+t)/z=(x+y+z+2015t)/t Tính A = (x+y)/(z+t)=(y+z)/(t+x)=(z+t)/(x+y)=(t+x)/(y+z)
Cho biết x/y+z+t = y/z+t+x = z/t+x+y = t/x+y+z
Tính C =( x+y/z+t ) + ( y+z/t+x) + (z+t/x+y) + (t+x/y+z)
Cho x/y+z+t=y/x+z+t=z/x+y+t=t/x+y+z. Chứng minh x+y/z+t+y+z/t+x+z+t/x+y+t+x/y+z có giá trị là một số nguyên
