Here is the solution:
From the left box to the right, allocate a, b, c, d to the boxes respectively and that will lead us to the following equations:
a+b= 8 ......eq1
a+c=13.......eq2
c-d=6 ........eq3
b+d=8........eq4

Solving eq3 and eq4 simultaneously by adding, we will be able to eliminate "d" and obtain the equation;
c+b= 14........eq5

Solving eq1 and eq2 simultaneously by subtracting, we will be able to eliminate "a" and obtain the equation;
c-b=5........eq6

Solving eq5 and eq6 simultaneously, we eliminate "b" by adding eq5 and eq6 and will be left with:
2c=19
c=19/2 or 9.5

subt the value of c into eq2 to get a
a+c= 13....eq2
a= 13- 19/2
a= 7/2 or 3.5

subt a= 7/2 into eq 1 to get b
a+b= 8...eq1
b= 8- 7/2
b=9/2 or 4.5

subt b= 9/2 into eq4 to get d
b+d= 8 ...eq4
d= 8- 9/2
Hence d= 7/2 or 4.5

Therefore, the required set of solution is
a= 3.5
b= 4.5
c= 9.5
d= 3.5


Check
3.5 + 4.5 = 8
3.5 + 9.5 =13
9.5 - 3.5 = 6
4.5 + 3.5 = 8

As you can see, the set of answers provided corresponds to the set out equations.

I was actually dresing up for work when I saw the thread and that was why I initially put a "brb". Solved it as soon I was settled down on my table. The virtual kiss ain't bad. It was well caught kiss. You can mention me whenever you have maths, puzzles, tough riddles etc. I like doing them.

Anytime it is your birthday, anyone that clicks on your profile will see it there that "today is your birthday" and there is usually a birthday caake symbol there as well.
