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!!!~

The correct answer is x = 2/5
Step-by-step explanation:
It is given an expression,
1/4x = 5/8
To solve the expression
The given expression is 1/4x = 5/8
(Cross multiply both sides we get)
8 = 5 * 4x
8 = 20x
20x = 8
x = 8/20
x = 2/5
Therefore the value of x = 2/5
The correct answer is x = 2/5
