First of all, you can also place the number 3 in column 1. (Look at box 9, and then figure out what that means for box 7 and finally for column 1).

Then you should look at row 6. You will find a pair in that row and after that you can fill in the number 3.

Paz

look at box 9 - which cells can 3 go in?

Now look at column 1. Which cells cannot have a 3 in them?
