D. x = 3 because 3+3 is 6 and that is over 2*3^2 which is 2*9 which means it is 6/18 then you divide both the numerator and denominator by 6 and that =1/3.

Answer: Option D x=3 is the solution to the given equation [tex]\frac{1}{x} = \frac{x+3}{2x^{2}}[/tex]

Explanation:

we will do the reciprocal first on both the sides we will get x=[tex]\frac{2x^{2}} {x+3}[/tex]

Now, x will cancell out from both sides in numerator we will get

1=[tex]\frac{2x}{x+3}[/tex]

x+3 =2x

x=3

Hence, solution for given equation is x=3.
