Required figure is attached in the picture below :
Answer:
2
Explanation:
Number of cards = 3
The number on first two cards are :
Card 1 = 4 ; card 2 = - 6
Number that must be on the third card to obtain a total score of 0
Represent third number by a variable, x
Sum of all 3 numbers equal 0
(4 + (-6) + x) = 0
4 - 6 + x = 0
-2 + x = 0
Add 2 to both sides :
-2 + x + 2 = 0 + 2
x = 2
Hence, value of the third card must be 2
