Answer 2

Answer:

From top left clockwise:

3.5, 4.5, 3.5 and 9.5

Step-by-step explanation:

Labelling boxes starting from top left going Clock wise as X, Y, B and A gives us following equations

1. X+Y = 8

2. X+ A = 13

3. Y+B = 8

4. A-B = 6

Adding all equations together

X+Y+X+A+Y+B+A-B = 8+13+8+6

=> 2X + 2Y + 2A = 35

TAKE 2 COMMON FROM 2X+2Y

=> 2(X+Y) +2A = 35

PLUG VALUE OF X+Y FROM EQ 1

=> 2(8) +2A = 35

=> 16 + 2 A = 35

= > 2A = 35 - 16

=> 2A = 19

=> A = 9.5

Plug in this value in eq 2 and 4 to get X = 3.5 and B = 3.5

Plug in value of X = 3.5 in equation 1 to get Y = 4.5

Ans: X= 3.5, Y= 4.5,B = 3.5, A = 9.5
