X=33/17
Here is how it works
By the way what you are working with is called improper factions, which is when the big number is placed over the smaller number.
Now 33/17 is also 1 16/17
35/17 is also 2 1/17
Now we can the proper fractions which are 1 16/17 and 2 1/17
1+2=3 and 16/17 + 1/17 equals 1
3+1=4
