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
Please mark my answer as the brainliest!!

Vihi2102: Please comment if any doubt
amanrajkol2002p47c6r: yea
amanrajkol2002p47c6r: can you give me in photo
chaitany2002: no dude its wrong
Vihi2102: Sorry y= 8-4.5=3.5
Vihi2102: 4.5+3.5=8
Vihi2102: Oh dam messed up in the end
Vihi2102: x = 13-9.5=3.5
Vihi2102: y=8 - 3.5 = 4.5
Vihi2102: I’m sooooo sorry for the confusion

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
