Answer 1

Answer:

4+4=8 ,19 -6 = 13 okay I guess

Answer 2

Answer:

The numbers in the boxes in the clockwise direction are respectively

3.5, 4.5, 3.5, 9.5

Step-by-step explanation:

x + y = 8 ............. (1)

u - v = 6 ...............(2)

x + u = 13 .............(3)

y + v = 8 ...............(4)

Four equations four unknowns, which can be solved

(2) + (4) ⇒ u + y = 14 .......... (5)

(3) - (5) ⇒ x - y = -1   ............ (6)

(1) + (6) ⇒ 2x = 7

or, x = 7/2 = 3.5

Therefore from (1)

y = 8 - 3.5 = 4.5

from (3)

u = 13 - 3.5 = 9.5

From (4)

v = 8 - 4.5 = 3.5
