Answer: x=3

Step-by-step explanation:

To solve this problem you must apply the proccedure shown below:

- Multiply both sides of the equation by 3:

$3(2x-3)=3(\frac{x^2}{3})\\6x-9=x^{2}$

- Now you must make the equation equal to zero as following:

$6x-9=x^{2}\\x^{2}-6x+9=0$

- Factor it, as you can see below. Therefore, you obtain the following result:

$(x-3)(x-3)=0\\(x-3)^2=0\\x=3$
