x+1/x=10/3

By taking LCM

x²+1/x=10/3

By cross multiplication

10x=3x²+3
3x²-10x+3=0

By spliting the middle term

3x²-x-9x+3=0

x(3x-1)-3(3x-1)=0

(x-3)(3x-1)=0

x=3 , x= 1/3

X + (1/x) = 10/3
(x²+1)/x = 10/3
cross multiplying..
3x² +3 = 10x
3x²*10x + 3 = 0
3x² -9x- x + 3 =0
(x-3) (x-(1/3)) = 0

therefore x=3 or x=(1/3)
