Need help solving the puzzle

Answer 1

$\LARGE{ \underline{\underline{ \sf{Required \: answer:}}}}$

Let gift box be x and the Christmas tree be y.

Then:

The equation formed by plugging x in place of gift box and christmas tree will be:

(1) 2x + y + 3 = 16

➛ 2x + y = 13

(2) 3x + y + 1 = 14

➛ 3x + y = 13

Subtracting (2) from (1), And we get:

➛ 3x + y - 2x - y = 0

➛ x = 0

Then, y = 13

We need to find:

• yx + x

= 13 × 0 + 0

= 0

Hence:-

• The cost of all the items will be 0. Congrats for Christmas Bingo!!!
