The answer is x=4, but I show you one way to solve it below.

Explanation:

First, move the 16 term to the right of the = sign, so that terms involving the variable are together on the left and the right side of the equation has only numbers. To do this, subtract 16 from both sidess

x23=5616

x23=46

Now, get rid of denominators by multiplying each side by 6

#2(x-2)=4

Divide both sides by 2

x2=2

Add 2 to each side

x=4
