Let the first box be x, second be y, and the one towards the left in the second row be z
x+y=8
so the second box in the second row will also be x
x+z=13
z-x=6
Add both equations
x+z+z-x=13+6
2z=19
z=9.5
x=13 - 9.5 = 4.5
y=6-4.5=1.5

Answer:
Step-by-step explanation:
First row
x + y = 8
Top left and bottom right = x
Left column
x + z = 13
Right column
y + x = 8
Second row
z - x = 6
----------------------------
(x + z) + (z - x) = 13 + 6
(x + z) + (z - x) = 19
x - x = 0
2z = 19
So
z = 9,5
x + z = 13
x + 9,5 = 13
x = 13 - 9,5
So
x = 3,5
x + y = 8
3,5 + y = 8
y = 8 - 3,5
So
y = 4,5
