Since we know that opposite angles in a parallelogram are equal, we can set angle D equal to angle B in order to solve for n: 4n-2=2n+32. First, you need to add 2 to both sides to get 4n=2n+34. Then, you need to subtract 2n from both sides to get 2n=34. Lastly, you need to divide both sides by 2 to get n=17.
I hope this helps.
