I think its correct
This is a simultaneous equation. its saying there are two numbers (x and y) that satisfy both equations. Rearrange the 2nd equation to get x=30/y and substitute this into the first equation to get y=(30/y) +13. solve this for y and then you can solve for x.
That is the x spot or the non existing spot it is there just to make sure you have the numbers in order right and so the sums for the multiplication equation do not collide
